When will the wheat be harvested three times?

Wheat should be sprayed once at jointing stage (middle and late March), booting stage (mid-April) and heading stage (after flowering 15 days or so).

The first spraying of wheat should be at the jointing stage of wheat turning green, and potassium dihydrogen phosphate and boron fertilizer can be applied appropriately at this time. If the leaves are yellow or infected with pests, you can also apply beta-cypermethrin to prevent them.

The second spraying time of wheat should be about 20 days before heading. At this time, in addition to reasonable potassium dihydrogen phosphate and boron fertilizer, phenylpropiconazole or prochloraz should be applied appropriately, and farmers with conditions can also spray brassinolide appropriately.

The third spraying of wheat should be about half a month after flowering. Besides rational fertilization, propiconazole, prochloraz, chlorpyrifos and imidacloprid should be sprayed.
