Which fungicide is best for wheat?
Triadimenol is similar to difenoconazole, but it provides excellent control of fall powdery mildew and very good control of fall infections of leaf rust or stripe rust in high mildew areas. In high mildew areas, it can often be used as a replacement for foliar mildew sprays in early spring (up to head emergence).

Which chemical method is used to prevent rust of wheat in the crop?
Explanation: pesticides are a chemical method for preventing wheat rust in the field.
What Weedicides use wheat?
Weedicides are used to control weeds in wheat. Clodinafop Propargyl 15% Metsulfuron Methyl 1% WP is the name of the weedicide used to control weeds in wheat. It is sprayed after 20-25 days of sowing the crop or in standing crop.
Is it OK to mix fungicide and insecticide?
Tank mixes can include a fungicide and an insecticide to control both fungus and insects at the same time, or a pesticide with fertilizer or two herbicides to increase weed control. However, unless a pesticide’s label expressly prohibits mixing, mixing is legal.
Which is an example of systemic fungicide?

Does a freeze hurt wheat?
Wheat is most vulnerable to freeze injury during reproductive growth, which begins with pollination during the late boot or heading stages, and even temperatures just below freezing can severely injure wheat at these stages, reducing grain yields significantly.
Why do they call it winter wheat?
Winter wheat must be exposed to a series of cooler temperatures early in the growth stage to survive through cold winters with subfreezing temperatures, a process known as “cold acclimation” or simply “hardening.”
Can wheat take a frost?
Wheat is a winter crop that can tolerate cold temperatures, so freezing temperatures between boot and flowering may cause leaf discoloration, spikes becoming trapped in the boot, floret sterility, and damage to the lower stems.
