METCONAZOLE-CONTAINING PESTICIDE COMPOSITION FOR PREVENTING AND CONTROLLING FUSARIUM HEAD BLIGHT AND APPLICATION THEREOF

摘要

The present invention relates to a pesticide composition for preventing andcontrollingfusarium head blight, which contains 1 to 150 parts by weight of jinggangmycinand 1 to 20parts by weight of metconazole per mu. The pesticide composition of thepresent inventionhas an obvious synergistic effect when used for preventing and controllingfusarium headblight, and can remarkably enhance the effect of preventing and controllinghead blight,increasing the ability of the human being in preventing and controlling headblight of triticeaecrops; the contamination level of DON toxin in grains is remarkably decreased,dosage, cost,environmental pollution and pesticide residue are reduced, the resistance ofwheat pathogenicfungi to metconazole is retarded, and fusarium head blight is prevented andcontrolled; thepersistent period of jinggangmycin is prolonged, the frequency of applicationis decreased, thepowdery mildew, rust, leaf blight and sheath blight of triticeae can also becontrolled, thelabor cost of pesticide application is reduced, the dosage of the chemicalpesticide is reducedgreatly, and the pesticide composition is environment-friendly.
