Pesticide application method capable of improving wheat yield

Abstract

The invention relates to a pesticide application method capable of improving the wheat yield. According to the method, Baitai, Oubo, Gaoqiao, Shileshi, Alika, Handilong, monopotassium phosphatem, microelement mixed liquor high efficiency and low toxicity agentia are adopted; the method is carried out in four stages: wheat seed dressing stage, wheat standing and jointing stage, wheat heading stage and wheat filling stage; as the pesticide is applied according to different growth stages of the wheat, more than 90% diseases of the wheat can be efficiently controlled, the quality and the yield are improved, the medium trace elements required for the middle and later periods of fertility of the wheat can be met, the premature senility of the wheat at the later period can be prevented, the resistance to natural disasters is enhanced, and the pesticide application method is particularly suitable for planting of wheat.

Description

technical field [0001] The invention relates to a pesticide application method for agricultural production, in particular to a pesticide application method for improving wheat yield. Background technique [0002] Common pests of wheat mainly include: wheat rust, powdery mildew, scab, sheath blight, viral diseases and aphids, wheat spiders, midges, leaf wasps, armyworms, underground pests, etc. Farmers who grow wheat need to apply pesticides to wheat during the process of planting wheat, mainly to prevent wheat disease and increase the yield of wheat. However, most of the following problems exist in the prevention and control of wheat diseases. First, most of them use a special pesticide Or chemical fertilizers are sprayed on the leaves of wheat, but most of them do not achieve the purpose of comprehensive control, resulting in low wheat yield; second, the control period is late, because the farmers' awareness of the disease is not high, when the wheat disease occurs seriousl...

Problems solved by technology

[0002] Common pests of wheat mainly include: wheat rust, powdery mildew, scab, sheath blight, viral diseases and aphids, wheat spiders, midges, leaf wasps, armyworms, underground pests, etc. Farmers who grow wheat need to apply pesticides to wheat during the process of planting wheat, mainly to prevent wheat disease and increase the yield of wheat. However, most of the following problems exist in the prevention and control of wheat diseases. First, most of them use a special pesticide Or chemical fertilizers are sprayed on the leaves of wheat, but most of them do not achieve the purpose of comprehensive control, resulting in low wheat yield; second, the control period is late, because the farmers' awareness of the disease is not high, when the wheat disease occurs seriously, Farmers can only find out that the best control period is often missed, and the control effect is not ideal. For example, the control of wheat sheath blight needs to be controlled in March every year, and farmers do not start control until April when they find that the leaf sheaths at the bottom of wheat roots are rotten. The optimum period for the prevention and control of wheat scab is 10% of wheat flowering, and the control period is less flexible and the time is short, and most farmers do not control until the time of grouting; the third is not to pay attention to combined with the control of diseases and insect pests to carry out topdressing outside the root; In terms of the choice of chemicals, the old ones are the main ones. The pesticides that have been used for decades are still commonly used. The fungicides Duoyinling, Fenxining, and Jinggangmycin are still widely used. The resistance of omethoate is very strong, and the bactericidal effect is not ideal. Omethoate, which is often used, is highly toxic and not safe for humans and animals.
