Problems solved by technology

Long-term use of a certain type of chemical pesticides can easily cause pests to develop resistance, resulting in a sharp increase in the amount of chemical pesticides used. Such a vicious circle will greatly increase the economic burden of farmers on the one hand, and seriously pollute the ecological environment of crops on the other hand.

Abstract

The invention discloses an azadirachtin and bacillus subtilis mixed water dispersible granule consisting the following substances in percentage by weight: 0.1-50% azadirachtin, 1-30% wetting agent, 5-30% binder, 0.1-30% disintegrant, 10-60% carriers. The invention belongs to the field of biopesticide, can prevent the drug resistance of pests, improve the application effect of the water dispersible granule, prevent various agriculture and forestry diseases, widen the application range of the water dispersible granule by utilizing the synergy relationship between the active component azadirachtin and the bacillus subtilis specifically; moreover, the water dispersible granule has no pollution or residue, high efficiency and low toxin; therefore, the water dispersible granule is beneficial to the ecological environment protection and the safety of people and animals.

Description

technical field [0001] The invention relates to an agricultural mixed water-dispersible granule, in particular to a water-dispersible granule mixed with azadirachtin and Bacillus subtilis. Background technique [0002] At present, a large number of chemical pesticides are used in agriculture. Due to their toxic and side effects, they have brought great harm and many negative effects to the protection of human beings, livestock and the natural environment. For example, long-term use will cause a series of problems such as human and animal poisoning, killing a large number of beneficial natural enemies, and destroying the ecological environment. Long-term use of a certain type of chemical pesticides can easily cause pests to develop resistance, resulting in a sharp increase in the amount of chemical pesticides used. Such a vicious circle will greatly increase the economic burden of farmers on the one hand, and seriously pollute the ecological environment of crops on the other ...
