Abstract

The invention discloses application of a sterilization composition containing captan and tebuconazole in prevention and treatment of FusaHum graminearum. The sterilization composition comprises effective active ingredients which are composed of a first active ingredient--captan and a second active ingredient--tebuconazole, wherein the weight ratio of the first active ingredient to the second active ingredient is 90: 1 to 1: 90; and the sum of the contents of the active ingredients accounts for 2% to 90% of the total weight of the composition. The composition may be made into agriculturally allowable dosage forms of a wettable powder, a water dispersible granule, a suspending agent, a dispersible oil suspending agent, a suspoemulsion, an ultra low volume liquid and a dispersible liquid. The sterilization composition provided by the invention has significant control effects on FusaHum graminearum.

Description

technical field [0001] The invention relates to the application of a bactericidal composition containing captan and tebuconazole in the prevention and treatment of wheat scab. The bactericidal composition consists of the first active ingredient captan, the second active ingredient tebuconazole and auxiliary agents The composition belongs to the technical field of pesticide application. Background technique [0002] Captan, English common name: captan, chemical name: 3a, 4, 7, 7a-tetrahydro-2-(trichloromethylsulfur)-1H isoindole-1,3-(2H)-dione. It can prevent and control a variety of diseases on fruit trees, vegetables and crops, and can also be used as a seed treatment agent or root irrigation to prevent stem blight, blight, and black spot. It is phytotoxic to certain varieties of apples and pears, and has effects on lettuce, celery, and tomato seeds. [0003] Tebuconazole, English common name: tebuconazole, chemical name: (RS)-1-p-chlorophenyl-4,4-dimethyl-3(1H-1,2,4-tria...
