Wheat diseases and pests in the middle and later stages mainly include powdery mildew, head blight, comprehensive leaf blight, red spider, wheat aphid, wheat leaf bee, midge, gramineous weeds, wild wheat, etc., which seriously endanger the growth of wheat and give wheat. Production and quality have a great impact. In the aspect of prevention and control, the principle of plant protection, which focuses on prevention, and integrated prevention and control, is based on agricultural prevention and control, and other measures are coordinated to minimize the harm of diseases and weeds.

First, the disease
1. Fusarium head blight: In the wheat heading and flowering stage, if it is forecasted for 3 days or more, rainy weather should be promptly prevented. 50% carbendazim WP may be used 500 times or 70% thiophanate-methyl WP may be used as 1000 times or 12.5% Fuguoli WP 2000 times foliar spray control.
2. Powdery mildew, rust: When the leafy disease rate exceeds 20%, when the leaf rust disease leaf rate reaches 2-4%, when the leaf rust disease leaf rate reaches 5-10%, immediately control, available 25% Fendi Ning 1000 times foliar spray control, severe plot 7 days before spraying 1-2 times.
3. Head smut, stem smut, and scattered head smut: In addition to the selection of disease-free superior seed and pesticide seed dressing, 50% carbendazim wettable powder 500 times or 70% is used for heading and flowering. Thiophanate-methyl wettable powder 1000 spray.
4. Synthetic leaf blight: When the diseased rate exceeds 15%, use 50% carbendazim WP 500 times or 70% thiophanate-methyl WP 1000 times or 25% chlorpyrifos 1000 times Surface spray, while adding 1% urea and 0.2% potassium dihydrogen phosphate, to protect the leaves, increase the weight of the role.
Second, pests
1. Starscream: When wheat has a single row of 33 centimeters and more than 200 red spiders, it is uniformly sprayed with 1.8% abamectin 1.8%, or 20% baicalin 1000-1500 or 40% dimethoate 1000-1500 times.
2. Wheat leaf bee: When the wheat leaf bee population is more than 30 per square meter, control with 4.5% cypermethrin 1000 times spray, generally do not need to control alone, control wheat aphid can be both concurrent and governance.
3. Midge: wheat midge, it is a devastating pest, the prevention and control strategy is based on prevention and control of the flood season, supplemented by adult control. The appropriate period for prevention and control in the flood season is April 20-25. The prevention and control index is a length, width, and depth of 1,02020 cm. Samples have more than 2 midge insects. The control method is 48% of Muscat, 150 ml of Le Siben EC or 5% of Le Sibu Granules. 3 kg or 2% of the granules 800-1600 g mixed soil 20-25 kg, evenly sprinkled in the wheat field when there is no dew, and then watering to improve the control effect. Adult stage prevention and control is to check the wheat ridge before heading and flowering of wheat. At a glance, the adult insects of 2-3 heads of adult midge or 10 nets of complexes with more than 20 adults should be controlled in time, and 25% of fast killing spirits should be 1500 times or 25%. Huifeng crack 1500 times or 3% acetamiprid 2000 times or 40% dimethoate 1000 spray.
Third, weed damage: weed control in the autumn to promote the use of chemical control, the prevention of bad effect of the remnants of the plot of weeds, timely removal of the wheat before flowering to prevent the maturity of grass seeds fall into the field continue to harm.
In the prevention and control of wheat diseases, weeds and weeds, we must adhere to the principle of one-spray and multiple-prevention measures, with more than 30 kilograms of water, and pay attention to spraying and spraying.
