Embodiment 1

[0011] Step 1: Before sowing wheat seeds, take 3 kg of 2.5% isofenphos-methyl granules per mu of wheat field, mix with 10 kg of fine soil, and then evenly spread it on the ground of the wheat field, and then plow the land of the wheat field;

[0012] Step 2: In the pupal stage of the midge, use 900g of 5% chlorpyrifos powder per mu of wheat field, mix with 25kg of fine soil, then spread it evenly in the wheat ridge, and water the wheat field after spraying;

[0013] Step 3: In the adult stage of midges, use 60ml of 40% phoxim emulsifiable concentrate per mu of wheat field, mix with 45kg of water, and then spray the wheat for 3 consecutive times with an interval of 3 days.

Embodiment 2

[0014] Embodiment two: step one: before wheat seed sowing, get 3.5kg of 2.5% isofenphos-methyl granules per mu of wheat field, mix with 10kg of fine soil, then spread evenly on the wheat field ground, then plow the wheat field land;

[0015] Step 2: In the pupal stage of midges, use 850g of 5% chlorpyrifos powder per mu of wheat field, mix with 25kg of fine soil, then evenly spread in the wheat ridge, and water the wheat field after spraying;

[0016] Step 3: In the adult stage of the midge, use 70ml of 40% phoxim EC per mu of wheat field, mix with 45kg of water, and then spray the wheat for 3 consecutive times with an interval of 3 days.

Abstract

The invention discloses a method for controlling wheat Sitodiplosis mosellana. The method includes the following steps: before sowing of wheat seeds, mixing 3-3.5 kg of a 2.5% isofenphos-methyl granular formulation and 10 kg of fine soil, evenly distributing the mixture to a wheat field per mu, and turning over a wheat field land; in a Sitodiplosis mosellana pupa stage, mixing 800-1000 g of 5% chlorpyrifos powder and 25 kg of fine soil, evenly distributing the mixture to wheat ridges, and then watering the wheat field; in a Sitodiplosis mosellana adult stage, adding 45 kg of water into 50-70 ml of 40% phoxim emulsifiable concentrate, and continuously spraying wheat for 3 times every 4 days. The method adopts a prevention first and treatment second strategy to control the Sitodiplosis mosellana, and can greatly improve the yield of the wheat.

Description

technical field [0001] The invention relates to a method for preventing and controlling wheat midges, which is applied in the technical field of wheat planting. Background technique [0002] Wheat midge is a destructive pest that damages wheat flower organs and sucks the slurry of wheat grains that are filling, causing shrunken grains and reduced production. When the damage is severe, it almost destroys production. Its damage directly threatens the high yield and harvest of wheat. Wheat midges basically have one generation per year, and grow larvae to cocoon in the soil to survive summer and winter. In the next spring, before and after the wheat festival, when there is enough rain, the overwintered larvae begin to move to the soil surface. At the booting stage of wheat, the larvae Gradually pupate, and adults flourish at the earing stage of wheat and lay eggs on the ears of wheat. Due to the harmful characteristics of midges, the control methods currently on the market are ...
