Blending medicament preventing and curing cercospora brown spot of peanut and using method thereof

Abstract

The invention discloses a blending medicament preventing and curing cercospora brown spot of peanut, comprising the following materials in parts by weight: 1-10 parts of diniconazole, 1-10 parts of carbendazim, 1-20 parts of GZM and 1500-24000 parts of water. The preparation ratio of diniconazole to carbendazim to GZM is 1:1:1-2, and the mass fraction ratio of mixture to water is 1:500-600. In the invasion initial stage of brown blotch, blending medicament is sprayed twice at the medicament spraying interval of 10-14 days. The invention can effectively prevent and cure cercospora brown spot of peanut, can obviously control peanut excessive growth, improve bean yield, perform the dual action of obviously preventing disease and inhibiting growth, and perform the function of one medicine with multiple purposes. In addition, pesticide dosage is reduced to lighten environment pollution and bring benefits for ecological balance. Physical protective agent GZM is added to perform certain physical protection action on peanut plants, prolongs pesticide effect time and reduces application times.
