Bacteria and pest killing compound agent for wheat

Abstract

The invention relates to the development and application of a bacteria and pest killing compound agent for wheat. The compound agent mainly consists of tebuconazole, triazolone and imidacloprid and can be prepared into missible oil, missible oil, wettable powder and the like. Demonstrated by biological test, the compound agent has obvious synergistic function for wheat stripe rust and erysiphe graminis and can also prevent and kill aphid. According to field experiments, the compound agent can achieve 90 percent of effect in preventing wheat leaf diseases, more than 90 percent of effect in preventing the erysiphe graminis, no less than 98 percent of effect in preventing and controlling wheat sitobion avenae. The compound agent has the functions of killing bacteria and pests, is conveniently used, saves work time, reduces cost and environment pollution, and actively responds to the national policy of energy conservation and emission reduction. Meanwhile, the compound agent has simple process, is easy to produce, can be directly transformed into a production capability and can obtain economic and social benefits as soon as possible.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a compound fungicide and insecticide for preventing and treating wheat rust, wheat powdery mildew and wheat aphid. technical background [0002] Wheat is the second largest grain crop in my country, with an area of ​​23 million hectares, second only to rice. There are 38 kinds of common diseases and 37 kinds of pests in the wheat growth period. Wheat rust and wheat powdery mildew rank the top two among the three major diseases of wheat, and wheat aphids rank first among insect pests. The harm of "two diseases and one insect" can lose 50% of the yield of wheat, and in severe cases may lead to extinction. Therefore, this "two diseases and one insect" has become the top priority in the prevention and control of wheat diseases and insect pests. [0003] For a long time, chemical agents have been the main means of prevention and control. Triazoles fungicides have been w...

AI Technical Summary

Problems solved by technology

[0004] There are always two major problems in the prevention and control of wheat diseases and insect pests. One is the long-term, large-scale and single use of chemical agents, which makes them resistant to insecticides, and the effect of disease prevention and pest control is not good.

The second is that during the long growth period of wheat, powdery mildew, rust, and aphids occur and harm at the same time. However, farmers often only adopt separate control methods for a single pest, resulting in labor-intensive, time-consuming, and labor-intensive measures.

The above-mentioned patents each have their own unique features, but in general, they either only focus on the bactericidal effect, or only emphasize the insecticidal effect, and seldom involve the prevention of the generation and development of drug resistance and the simultaneous treatment of "two diseases" with one application. Unified consideration of "one pest" or multiple pests and diseases
