Abstract
The invention relates to a synergetic interaction pesticide composition containing benzothiostrobin and prothioconazole. The weight ratio of benzothiostrobin to prothioconazole is (1:30) to (30:1), and the preferable weight ratio is (1:10) to (5:1). The pesticide composition can be used for preventing and treating various crop diseases, such as false smut, rice blast, powdery mildew, downy mildew and sclerotinia sclerotiorum, and has an obvious synergetic interaction effect within the ratio range. The pesticide composition can be prepared into any of pesticide formulations including but not limited to one of emulsifiable concentrate, wettable powder, a water dispersible granule, a suspending agent, an emulsion in water, a microemulsion and a seed treatment formulation through conventional methods in pesticide preparation processing.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic pesticide composition containing penthiostrobin and prothioconazole and a method for preventing and treating crop diseases. Background technique [0002] Rice false smut, also known as blue powdery mildew and pseudo smut, is a fungal disease. With the promotion of some dwarf compact rice varieties and the improvement of fertilization level, the occurrence of this disease has become more and more prominent. The empty and shriveled grains of diseased ears significantly increase, and generally can reduce production by 5% to 10% after the onset. Rice false smut mainly occurs in the stage of heading and flowering of paddy rice, and harms the upper part of the grain on the ear, at least 1 to 2 grains per ear, and seriously up to 20 to 30 grains. Occurrence rule: this disease mainly survives the winter in soil with sclerotia, and germinates to form sporozo...
