Problems solved by technology

[0004] The prevention and control of "two diseases and one insect" in wheat has always faced two major problems. One is the long-term, large-scale, and single use of chemical agents, which has produced resistance to wheat rust and powdery mildew. The disease prevention effect is decreasing year by year, and the control cost is increasing
The second is that during the wheat growth period, powdery mildew, rust and aphids are often mixed hazards. However, a single control method is often only adopted for a certain pest, resulting in labor-intensive, time-consuming and laborious.
The above-mentioned patents each have their own unique features, but in general, they only focus on the effect of sterilization, and seldom consider the prevention of resistance and the simultaneous prevention and treatment of "two diseases and one insect"

Abstract

The invention relates to research and application of a bactericidal and pesticidal compound agent for wheat. The compound agent for wheat is mainly prepared from diniconazole, triadimefon and imidacloprid and can be prepared into emulsifiable oil, microemulsion, wettable powder and the other formulations. The biological tests show that the compound agent for wheat has obvious synergism on wheat rust and wheat powdery mildew and also has a favorable curative effect on wheat aphids. The field tests show that the compound agent for wheat achieves the wheat rust prevention effect of 90 percent, the wheat powdery mildew prevention effect of over 90 percent and the sitobion avenae prevention and control effect of no less than 98 percent. The compound agent for wheat has bactericidal and pesticidal effects, is convenient to use, time-saving and labor-saving, ensures that the cost is lowered and the environmental pollution is reduced, and actively cooperates with the energy saving and emission reducing state policy. In addition, the compound agent for wheat is simple in preparation process, is easy to prepare and can be directly converted into productive force to gain 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. Background technique [0002] Wheat is the second largest grain crop in my country, with an area of ​​more than 20 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, wheat powdery mildew and wheat aphids are the most serious damage. In severe years, the production can be reduced by 50%, and even 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, the main means of pest control is chemical agents. Triadimefon, as the earliest commercialized triazole fungicide, has become the main species in the whole control process; however, studies h...
