K2
GENERAL COMMENTS : ‘The effects of K2 on plant growth can result in yield increase and a
reduction in early lodging from a spring application. This control of lodging is more consistent in wheat
than in barley.’
TIME OF APPLICATION TO AUTUMN SOWN CROPS (WHEAT AND BARLEY)
Apply K2 during tillering, but not later than leaf sheath erect stage (when the leaf sheaths on half of the
main shoots have reached 5cm (2") measured from ground level to the base of the uppermost leaf blade)
but before the first node is detectable (Zadoks 31). This is likely to be between mid-February and mid-
April. Best results have been obtained from applications made before the end of March in all autumn
sown crops.
TIME OF APPLICATION TO SPRING SOWN CROPS (WHEAT ONLY)
Apply K2 during tillering, but before the first node is detectable on half of the main stems. This will
usually mean treating the crop between 15 and 35 days after 50% emergence, especially in late drilled
spring crops.
RATE OF APPLICATION
WINTER WHEAT Apply K2 at 1.0 litres per hectare (0.7 pints per acre)
SPRING WHEAT Apply K2 at 0.9 litres per hectare (0.64 pints per acre)
WINTER BARLEY Apply K2 at 1.25 litres per hectare (0.9 pints per acre)
APPLICATION VOLUME
Apply the recommended rate of K2 in at least 200 litres of water per hectare (18 gallons per acre).
MIXING
Shake well before use. Add K2 to a half-filled tank. Top up tank to the required volume and ensure
thorough mixing before and during spraying.
CAUTION
Do not use in tank mixture with liquid nitrogen fertiliser.
APPLICATION CONDITIONS
Do not apply K2 to crops under stress from waterlogging, drought, or nutrient deficiency. In hot, dry
weather a better result might be obtained from application in the early morning or evening.
CAUTION
Although K2 may be used under normal seasonal temperature (down to 1° C) and ground conditions, it
should not be sprayed onto plants covered with frost and requires two hours before rain or frost occurs
for a good effect to be obtained. Do not allow K2 to drift onto neighbouring crops.
UNDERSOWN CROPS
K2 may be used on crops undersown with clovers and grasses.
VARIETAL RESTRICTIONS
There are no varietal restrictions on the use of K2
SEED CROPS
K2 may be used on all varieties of wheat and barley grown under the Seed Certification Scheme but
growers are advised to consult the guidelines laid down in the Seed Certification Scheme’s
“Certification of Seed of Wheat, Barley and Oats”.

K2
USE OF STRAW
There are no restrictions on the use of straw from crops treated with K2.
