The invention discloses a mixed pesticide for preventing and controlling melasma and cercospora brown spot of peanut. The pesticide is prepared from the following raw materials in parts by weight: 6-18 parts of propineb, 1-3 parts of tebuconazole and 500-12600 parts of water. The dosage of propineb is 30g / mou, and the dosage of tebuconazole is 5g / mou. The propineb and the tebuconazole are matchedin the weight ratio of 6:1 per mou, and then 500-600 times of solution is added. The pesticide is applied twice in the primary disease incident period, and the interval of the pesticide application is 10-14 days. The invention can effectively control the peanut melasma, but also can obviously inhibit the cercospora brown spot of peanut, thereby achieving the purpose of one pesticide with multiplefunctions. The invention reduces the pesticide applying amount, prolongs the effect time, reduces the pesticide applying times, lightens the environment pollution, and is favorable for the ecologicalbalance.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound medicament for preventing and controlling peanut black spot and brown spot disease and a use method thereof. Background technique [0002] Peanut black spot, also known as late spot, commonly known as "black jaundice" and "black astringent" disease, is the most common leaf fungal disease in peanut production areas at home and abroad. The peak of incidence mostly occurs in the middle and late stages of peanut growth, so it is called "late spot" disease. It often causes a large number of leaves to fall on the plant, resulting in hindered pod development and a sharp drop in yield. Peanut black spot lesions are dark brown, usually without a yellow halo, or with a narrow, inconspicuous pale yellow halo. On the lesion on the back of the leaf, there are usually many black dots (spores) in the shape of concentric rings, and there is a layer of dark brown mold, that is, th...
