What diseases and pests should be controlled in early spring wheat?

What diseases and pests should be controlled by early spring wheat? Please give guidance to early spring wheat to control the following diseases and insect pests: control sheath blight and total erosion disease after the wheat turns green in late February, use 12.5% WP 20g / mu or 15% WP 50g / mu to water 50kg / mu, spray evenly on the base of the stem to control wheat sheath blight. For the land with total erosion disease, the incidence of spike stage can be reduced by spraying the base of wheat stem with 15% vermicellin wettable powder 150 grams to 75 kilograms of water per mu. In the fields where underground pests occurred in the first and middle of March, 40% phoxim EC was used to irrigate the roots, and the application area was appropriately expanded. Chemical weeding and weed control should grasp the word "early". Wheat fields dominated by broad-leaved weeds such as Artemisia annua, shepherd's purse and Miwa can use 75% benzosulfuron dry suspension 1: 1.8 grams per mu; wheat fields dominated by Gramineae weeds such as Aegilops taeda, wild oats, brome, etc., use 6.9% Lima emulsion 60ml / mu or 3% Shima EC 25ml / mu. For serious fields such as pig calamity, mother-in-law, etc., 20% is used to increase EC 50ml / mu; mixed fields of broad leaves and Gramineae weeds are sprayed with 3.6% Kushima 20ml / mu and 30kg / mu of water for stem and leaf spray control, so as not to re-spray or leak spray. In order to prevent drug damage to the next crop, the time of application must be before March 10. Click to get more wheat planting technology click to get more grain planting technology
