The wheat orb spider is aggressive, sucking wort and destroying leaves and stems.

The farmers were extremely anxious, and all the Huifeng bombs were cleared.

With the gentle caress of the spring breeze, the wheat fields have gradually entered the season of turning green.

The soil moisture in the wheat fields this year is suitable, and the sowing time is earlier than in previous years, so the wheat population density is relatively high. With the recent rise in temperatures, some wheat fields have been severely attacked by wheat orb spiders.

01 Wheat Field--Wheat Spider

Wheat-ear spiders belong to the class Araneae. Spider mites prefer dark and humid environments, and temperatures of 8 to 15 degrees are the best time for them to be active.

They will suck the sap of wheat, causing the leaves to gradually wither and turn yellow, and even spread yellow mosaic virus disease. If it is not prevented and controlled in time, wheat will face serious risks of large-scale yield reduction.

To protect the greenness of wheat, it is urgent to prevent and control wheat orb spiders! Farmers are hereby reminded to

pay attention to the following prevention and control points

02 recommended medications and methods

Recommendation: Huifeng Little Bomb

(22% thiamethoxam, lambda-cyhalothrin microcapsule suspension, 10% biphenyl, clothianidin)

Timing of application

Since wheat orb spiders are only active on wheat leaves when the temperature rises, it is recommended to apply pesticides during the hottest period of the day.

Adjust water consumption

For denser wheat fields and plots with serious outbreaks of wheat orb spiders, it is recommended to use one and a half to two barrels of water per acre for fertilization. medicine.
