PLANT PROTECTION 1 – Pests, Diseases and Weeds
NON-SELECTIVE AND SELECTIVE INSECTICIDES
Broad & narrow spectrum insecticides
There is a wide range between the two extremes of non-selective and selective products, also some insecticides
can be used selectively, eg fruit fly baits (spinosad).
NON-SELECTIVE ACTIVE
INSECTICIDES
Broad spectrum
SELECTIVE
INSECTICIDES
Narrow spectrum
AGAINST A WIDE RANGE OF PEST AND BENEFICIAL INSECTS
Extensive repeated use of non-selective insecticides may result in upsurges
of pest species due to the reduction in populations of parasitic and predatory
insects, eg the use of cabaryl repeatedly to control codling moth on apples may
result in outbreaks of twospotted mite.
Other non-selective insecticide/miticides include:
Confidor (imidacloprid)
Folimat (omethoate)
Lebaycid (fenthion)
Maldison (malathion
Mavrik (tau fluvalinate)
Regent (fipronil)
Rogor (dimethoate)
Success , Entrust (spinosad)
Talstar (bifenthrin)
ONLY ACTIVE AGAINST SOME SPECIES OR SOME STAGES OF INSECTS
Selective insecticides may not kill off natural enemies preventing upsurges of new
pests and so are useful in IPM programs.
Some are bio-pesticides, eg Dipel ® (Bacillus thuringiensis), and are less toxic, not
many are available.
Some may have to be applied more frequently.
A wider range of pesticides may have to be stored and applied.
Examples of selective insecticides/miticides include:
Fruit fly lures and baits (many) - Fruit fly (adults)
Isomate C-S Pheromone (tiers) - Codling moth (adults)
Dipel (Bacillus thuringiensis) - Some leafeating caterpillars
Insegar (fenoxycarb)
- Codling moth
Vivus (virus)
- Corn earworms (Helicoverpa spp.)
Pirimor (pirimicarb)
- Aphids (nymphs and adults)
Greenguard (Metarhizium sp.) - Locusts and grasshoppers
Omite (propargite)
- Mites (adults and nymphs)
Apollo (clofentenzine)
- Mites (ovicide, nymphs)
Calibre (hexythiazox)
- Mites (ovicide)
Pyranica (tebufenpyrad)
- Mites (all stages)
Avid (abamectin)
- Mites, native budworm on cotton
Aramite , Floramite (bifenazate) - Mites
