Q U A D R I S 14

Quadris Means Quality in Tomatoes

Quadris fungicide has become the gold standard for

disease control in tomato crops. The systemic properties

of Quadris allow the active ingredient, azoxystrobin, to

move within the plant’s xylem. This systemic activity is

known as the Quadris X-Factor TM and provides an even

distribution of Quadris in the foliage and into newly

formed leaves for better disease control. This also

provides excellent rainfastness. When applied as a

foliar spray, the slow, steady uptake of Quadris keeps

a sufficient amount of fungicide on leaf surfaces to

protect the plant from infection by preventing

spore germination.

Integrated Pest (Disease) Management: Quadris should be integrated into an overall disease

management strategy that includes proper selection of varieties with disease tolerance, removal

of plant debris in which inoculum overwinters, plant residue management, crop rotation and

proper timing and placement of irrigation.

Resistance Management: When Quadris is being applied for the control of early blight, late blight,

Septoria leaf spot and/or anthracnose, no more than one foliar application of Quadris or other QoI

fungicides should be made before alternating with a fungicide with a different mode of action. If

late blight should occur during an early blight spray program, switch immediately to the late blight

spray program beginning with a fungicide that has a different mode of action. Do not make more

than five foliar applications of Quadris or other QoI fungicides per acre per year.

Application Directions: Quadris applications should begin prior to disease development and continue

throughout the season following the resistance management guidelines. For late blight, Quadris

should be applied at a five- to seven-day interval. For all other tomato diseases, Quadris should be

applied on seven- to 21-day intervals. Applications may be made by ground, air or chemigation.

Use of an adjuvant may result in severe phytotoxicity.

Quadris should not be applied until 21 days after transplanting or 35 days after seeding.

Do not apply more than 0.6 lb. a.i./A per season of products containing azoxystrobin.

Quadris may be applied the day of harvest (zero-day preharvest interval (PHI)).

20.0 lbs./A Applicator Settings: It is important to calibrate each granular applicator before its use. Even after calibration, check

the actual application rate under your operating conditions.

Application Instructions: Damping-off (Pythium spp.): Apply 20.0 lbs. per treated acre uniformly over the surface of

the soil at planting. If natural rainfall is not expected before the seeds begin germinating, Ridomil Gold GR should be

incorporated mechanically with ½ to 1 inch sprinkler irrigation. For banded applications, a 7-inch band is recommended.

Root and Fruit Rot (Phytophthora spp. and Pythium spp.): Additional applications can be made as soil surface applications

under the vines to provide control of root and fruit rot. If only one application is planned, apply 20.0 lbs. per treated

acre under the vines four weeks after the planting application to four weeks before harvest, depending on the

expected occurrence of the diseases. If root and fruit rot is a problem throughout the growing season or the occurrence

of diseases cannot be predicted, make two additional applications at 10.0 lbs. per treated acre under the vines, one

application four to six weeks after the planting application and another four weeks before harvest. If rainfall is not

expected within three days of the application, follow as soon as possible with 1 /2 to 1 inch overhead irrigation.

Ridomil Gold GR can be shanked into the beds with fertilizer. For calculating the amount of Ridomil Gold GR needed

per acre, apply the same amount as would be applied on a 7-inch band at 20.0 lbs. per treated acre. To obtain uniform

disease control, Ridomil Gold GR must be mixed uniformly with the fertilizer.

To avoid possible illegal residues, do not apply more than 40.0 lbs. per treated acre per season, and do not apply

within seven days of harvest. Do not use Ridomil Gold GR for disease control in greenhouse or field-grown

vegetable bedding plants.

T O M AT O E S


T O M AT O E S

Disease Cycle

Anthracnose is primarily a disease of ripe and

overripe fruit. The fungus overwinters as microsclerotia

on plant debris, which germinates and produces conidia

when conditions are wet and warm. The fungus may

infect fruit resting on the soil surface or it may be

rain-splashed to fruit higher up in the canopy. Infection

may occur while fruit is immature, but symptoms are

not expressed on the fruit until it matures and ripens.

Conditions for Development

Optimum conditions for infection include

temperatures from 68º to 75º F combined with free

moisture. Dissemination is favored by splashing

rain and overhead irrigation.

The bacterium that causes bacterial speck is

seed-borne but the importance of seed-borne inoculum

is not known. The bacterium is disseminated by

splashing rain and by machinery. The bacterium

may also survive for many weeks in crop residue.

Bacterial speck is a polycyclic disease.

Tiny dark lesions (smaller than

1 mm in diameter) may develop on

fruit. The tissue around each fruit

speck may be a more intense green

than unaffected areas, resulting in

a dark green halo around the spot.

Conditions for Development

High humidity, rainfall and temperatures

between 64º to 75º F favor disease development.

Bacterial Spot – Xanthomonas campestris

Symptoms

On leaves, stems and

fruit, small lesions are

generally brown and

circular and less than

3 mm in diameter.

Immature lesions look

water-soaked when

wet with rain or dew.

Fruit lesions start

as tiny raised blisters.

They increase in size

and become brown

and scab-like.

T O M AT O E S


T O M AT O E S

Disease Cycle

Bacterial spot can survive on tomato volunteers,

diseased plant debris and seed. It may be disseminated

on seed and within a field by rain splashing, transplant

clipping, or by workers or equipment moving through

the field. Bacterial spot is a polycyclic disease.

Conditions for Development

Disease development is favored by temperatures

of 75º to 86º F and extended periods of rainfall.

Black Mold – Alternaria alternata

Symptoms

Light to dark brown

lesions on the surface

of ripe fruit range from

small flecks to large

sunken lesions. During

warm, humid weather,

the fungus sporulates

to form a black velvetlike

layer on the lesion

surface.

T O M AT O E S


T O M AT O E S

Disease Cycle

Black mold survives on infected tomato debris in

the soil. Spores are disseminated via wind or splashing

water. Infection occurs when spores are blown onto

plants or when plants contact infested soil. The

fungus can infect fruit through wounds or other

damaged tissue.

Conditions for Development

Because free water is required for spore germination

and infection, black mold usually occurs following rains,

heavy dew or overhead irrigation. Symptoms may be

observed within four to five days after infection during

optimal environmental conditions that include

temperatures between 75º to 82º F.

B L A C K M O L D

Buckeye Rot – Phytophthora parasitica, P. capsici and P. drechsleri

Symptoms

A white cottony fungal

growth may appear on

lesions under high

moisture conditions.

Fruit lesions often

show a pattern of

concentric rings of

alternating dark brown

and light brown bands.

T O M AT O E S


T O M AT O E S

Disease Cycle

Buckeye rot infection occurs when fruit contacts

soil-borne inoculum, either by resting on the soil

surface or by mud splashing. The buckeye rot fungus

produces sporangia that give rise to zoospores under

optimal environmental conditions. The spores can

infect directly through the tomato skin. The pathogen

may be disseminated by surface water movement

and/or rain splashing.

Conditions for Development

Buckeye rot is most common during periods of

prolonged warm, wet weather. Widespread losses

may develop in conditions of excessive soil moisture

and soil temperatures of 64º to 86º F. Soil that holds

water for five hours or longer due to compaction or

poor drainage favors infection.

B U C K E Y E R O T

D A M P I N G - O F F 40

Damping-off – Pythium spp.

Symptoms

Seed decay or seedling

death prior to emergence

from the soil; death of

emerged seedling or

transplants as roots rot;

lower stems appear

water-soaked and

shriveled at the soil

line, followed by plant

wilt and death may occur.

T O M AT O E S


T O M AT O E S

Disease Cycle

Species of Pythium naturally inhabit the soil.

Infection in plant tissue is influenced by soil moisture,

soil temperature, pH, cation composition, light and

the presence of other organisms.

Conditions for Development

Optimum conditions for infection include wet soils

during seeding through the first two weeks after

transplanting. Soil moisture near saturation stimulates

mycelium vegetative growth. Plants are more

susceptible under these conditions: too high or too

low temperatures; excessive moisture; poor quality

light or unbalanced nutrition.

D A M P I N G - O F F

Early Blight – Alternaria solani

Symptoms

Immature lesions are

small and brownish black,

often with a yellow halo,

and usually occur on older

foliage. As lesions enlarge,

concentric rings may be

observed.

Stem lesions on seedlings

are dark, slightly sunken,

and have concentric

rings and light-colored

centers. Stem lesions may

girdle the plant, causing

collar rot.

T O M AT O E S


T O M AT O E S

Fruit lesions grow large and

usually have concentric rings.

Diseased areas appear leathery

and may be covered by a velvety

mass of black spores.

Disease Cycle

The early blight fungus survives between crops on

soil debris, on seed and on volunteer tomato plants

and other solanaceous hosts. Primary infection occurs

early in the season from conidia that are rain-splashed

onto new seedlings. Lesions are visible two to three

days after infection. Conidia formed on lesions serve

as a secondary inoculum and are wind-disseminated.

By late season, under favorable

conditions for disease development,

premature defoliation may occur.

Conditions for Development

Periods of mild, rainy weather are ideal for infection.

Conidia require free moisture for germination that

can occur in just 35 to 45 minutes at temperatures of

82º to 86º F. Heavy dew or frequent rains are necessary

for abundant sporulation. Early blight is usually less

severe on tomatoes grown under high fertility.

E A R L Y B L I G H T

Gray Leaf Spot –

G R A Y L E A F S P O T 44

Stemphylium solani, S. floridanum and

S. botryosum f.sp. lycopersici

Symptoms

Immature lesions are

barely visible and typically

limited to the leaf surface

itself. Circular to oblong

brownish black specks are

randomly scattered over

the leaf surface and are

unrestricted by veins.

Occasional lesions

develop on petioles and

stems that are linear and

parallel to the stem itself.

Mature leaf lesions can

reach 2 to 4 mm or more in

diameter and may coalesce,

killing large areas of the

leaf blade. The center of

leaf lesions may dry out

and crack. The entire

leaf may yellow and

eventually defoliate.

T O M AT O E S


T O M AT O E S

Disease Cycle

Gray leaf spot often occurs during the first true-leaf

stage of plant development. The fungus remains viable

from season to season on infected plant debris or on

other plant hosts such as pepper, horsenettle, etc.

Infection may occur in seedbeds or in field-seeded

seedlings. Conidia serve as both primary and secondary

inoculum and are disseminated by the wind or during

transplanting. Symptoms may occur within five days

of infection.

Conditions for Development

The optimum temperature for spore germination

is 78º to 80º F. Spores germinate quickly under warm,

moist conditions with extensive growth in a single

night. Optimum temperature for sporulation is

73º to 80º F.

G R A Y L E A F S P O T

45


G R A Y M O L D 46

Gray Mold – Botrytis cinerea

Symptoms

Sporulation of the

fungus from infected

necrotic tissue produces

a fuzzy, gray-brown

appearance. Lesions may

girdle the stem and cause

the plant to wilt above

the lesion.

Lesions on fruit are

typical of soft rot with

decayed regions. Skin

ruptures and sporulation

occurs in the center of

the decayed area.

T O M AT O E S


T O M AT O E S

Disease Cycle

The disease survives from season to season as

sclerotia on woody plant tissue or as saprophyte on

organic matter in soil. In addition, the fungus has a

wide host range and may survive on these hosts.

Conidia serve as secondary inoculum and are

disseminated by wind. Gray mold of foliage is usually

associated with some type of wounding or injury and

primarily affects mature plants with a dense canopy.

Conditions for Development

Infection occurs in cool weather and does not require

prolonged periods of high humidity. The optimum

temperature for infection is 64º to 73º F. Plants grown

in acidic, sandy soils with high water content are

particularly susceptible to gray mold.

G R A Y M O L D

47


L A T E B L I G H T 48

Late Blight – Phytophthora infestans

Symptoms

Young leaf lesions first

appear as water-soaked

areas on the leaflets that

enlarge quickly and turn

pale green to brown.

In moist weather, the

lesions on the undersides

of the leaf may show a

moldy, gray to white

growth, which is the

sporulation of the fungus.

T O M AT O E S


T O M AT O E S

As lesions mature, they turn

brown and cause general leaf

dieback.

Disease Cycle

Late blight survives on volunteer plants and on

abandoned plant material, such as cull piles. Sporangia

serve as the primary inoculum and are carried by wind to

other plants. Sporangia may germinate directly and infect

the plant, or, if temperatures are 54º to 59º F, sporangia

may produce zoospores that in turn infect the plant.

When conditions are favorable, the disease develops so

fast it appears as if the crop has been frost-damaged.

Fruit lesions appear as dark

olive, greasy spots that may enlarge

to cover the whole fruit.

L A T E B L I G H T

Conditions for Development

The disease is most active during cool, moist weather,

especially cool nights and warm days. Optimum conditions

for sporulation are 91 percent to 100 percent humidity

and 64º to 72º F. Optimum temperatures for zoospore

formation and germination are 54º to 59º F.

Temperatures above 86º F are unfavorable for disease

development, although the pathogen can survive.

P O W D E R Y M I L D E W 50

Powdery Mildew – Leveillula taurica

Symptoms

The most commonly

seen symptoms of

powdery mildew are

light green to bright

yellow lesions on the

upper surface of the leaf.

Necrotic spots may

develop in their centers.

A light powdery layer

may cover the lesion on

the leaf surface. Heavily

infected leaves die but

usually do not drop from

the plant.

T O M AT O E S


T O M AT O E S

Disease Cycle

Powdery mildew probably overwinters on weed

hosts. Conidia, the primary source of infection, are

wind-borne and serve as both primary and secondary

inoculum. Powdery mildew is a polycyclic disease.

Conditions for Development

Conidia can germinate in a wide range of

temperatures, from 50º to 95º F. Infection is favored by

temperatures under 86º F and high relative humidity.

Once infection is established in a tomato leaf,

temperatures above 86º F can speed up symptom

development and death of leaf tissue.

S E P T O R I A L E A F S P O T 52

Septoria Leaf Spot – Septoria lycopersici

Symptoms

The first symptoms are

usually visible on lower

leaves after the first fruit

sets and may also appear

on stems, petioles and

the calyx. Disease spreads

upward, from oldest to

youngest growth. Fruit

infection is rare.

The centers of leaf

lesions are usually dotted

with black pycnidia and

often have a narrow

yellow halo. Lesions can

enlarge to 5 mm in

diameter. Numerous leaf

lesions can cause infected

leaves to turn chlorotic,

then brown and wither.

T O M AT O E S


T O M AT O E S

Disease Cycle

Septoria leaf spot overwinters on infected tomato

debris or on stakes or cages. Conidia, the primary

inoculum, are spread by splashing irrigation water,

rain, or by workers and equipment. Symptoms may

appear within six days after inoculation, with pycnidia

visible about 14 days after inoculation. Septoria leaf

spot is a polycyclic disease.

Conditions for Development

Optimum temperatures between 68º to 77º F encourage

infection and symptom development. Long periods of

high relative humidity, high temperatures and leaf

wetness are ideal conditions for disease development.

S E P T O R I A L E A F S P O T

S O U T H E R N B L I G H T 54

Southern Blight – Sclerotium rolfsii

Symptoms

Infected plants suffer

a sudden and permanent

wilt of all aboveground

parts.

Brown to black stem rot

appears on plant parts in,

on or near the soil line.

Lesions develop rapidly,

completely girdling the stem.

Under moist conditions,

white mycelium develops

on lesions and extends up

the stem of mature plants.

Tan to reddish brown

sclerotia averaging 1 to

2 mm in diameter appear

on the maturing lesion.

T O M AT O E S


T O M AT O E S

White mycelium and

sclerotia are usually

observed in and on

infected fruit.

Disease Cycle

The fungus infects fruit that comes into contact

with infested soil. Fruit lesions appear sunken and

slightly yellow with a ruptured epidermis. Lesions are

water-soaked, soft and often star-shaped. Infected fruit

collapses within three to four days. Brown lesions with

surface mycelium appear on foliage that contacts

infected soil. The fungus can survive for several years

as sclerotia in soil and on host debris. Sclerotia serve

as the primary inoculum. The pathogen may be

disseminated through soil movement by equipment

or by water. Southern blight is a monocyclic disease.

Conditions for Development

Optimum conditions for infection include moist

air and temperatures between 86º to 95º F.

S O U T H E R N B L I G H T

T A R G E T S P O T 56

Target Spot – Corynespora cassiicola

Symptoms

Small water-soaked

lesions appear on the

upper leaf surface. They

gradually increase in

size, becoming round and

pale brown. Conspicuous

yellow halos develop.

Lesions may coalesce,

causing tissue collapse.

Petiole and stem lesions

are brown and oblong

and may girdle and kill

leaflets.

On young fruit, lesions

first appear as dark,

pinpoint brown spots.

They may enlarge and

develop into sunken

lesions. Ripe fruit

develops large round

lesions with pale brown

centers, which may crack.

T O M AT O E S


T O M AT O E S

Disease Cycle

The fungus has a very wide host range and probably

overwinters as mycelium and conidia on infected plant

debris. Conidia serve as primary and secondary inoculum.

Spores are most likely disseminated via splashing water

and wind. Target spot is a polycyclic disease.

Conditions for Development

Optimum conditions for disease development

include temperatures from 68º to 82º F and long

periods (16 to 44 hours) of high moisture. Infection

occurs at 60º to 90º F.

T A R G E T S P O T

W H I T E M O L D 58

White Mold (Sclerotinia Stem Rot) – Sclerotinia sclerotiorum

Symptoms

Infected stems are soft

with a light gray bleached

appearance.

Hard, black sclerotia

with white interiors

readily form inside stems.

The sclerotia assume the

elongated shape of the

stem cavity or take on a

tubular form. White mold

occurs on plants during

flowering. Infection

begins in leaf axils or in

stem joints where petals

have fallen and lodged,

producing water-soaked

areas that eventually die.

T O M AT O E S


T O M AT O E S

Disease Cycle

The fungus overwinters as sclerotia in soil and

on infected plant debris. The sclerotia give rise to

spore-producing bodies called apothecia in early spring.

Apothecia produce ascospores that serve as primary

inoculum for disease development. Ascospores are

disseminated via wind. The fungus can also enter

mature plants at the soil line. Mycelial growth spreads

between lush, overlapping plants, killing large circular

areas of infected plants within the field. Infected fruit

appears gray and rapidly breaks down in a watery rot.

The disease is generally monocyclic. However, disease

spread from plant to plant may occur via contact of

healthy plants with diseased plants or with the

fungus mycelium.

Conditions for Development

Cool, moist conditions with high humidity and free

moisture favor disease development. Long periods

of continuous wetness are necessary for ascospore

and plant tissue infection and lesion expansion.

Poor air circulation and moisture retention promote

disease development. White mold is more prevalent

in low-lying areas, in fields adjacent to heavily

wooded lots and in crops with lush vegetation.
