AI Technical Summary

Problems solved by technology

Due to the wide variety of these fungal diseases, complex symptoms, and rapid spread, it is more difficult to control and seriously affect the yield and quality of rice.
At present, the fungicides commonly used in rice fields and transplanting fields have developed rapid resistance to fungicides, and their bactericidal spectrum is limited. Fungicides with a single active ingredient can no longer completely and effectively control the occurrence of rice diseases.

Abstract

The invention relates to a paddy field composite bactericide containing flutriafol, isoprothiolane and flusilazole, and the application thereof. The bactericide comprises three main effective ingredients, namely flutriafol, isoprothiolane and flusilazole in the mass ratio of 0.1-20:0.1-30:0.1-15 correspondingly. Based on a large number of special researches, the inventor of the invention mixes flutriafol, isoprothiolane and flusilazole in a suitable ratio to successfully play the advantages of the three effective ingredients to the limit. Meanwhile, the comprehensive prevention and control defects of a single-dosage bactericide to crop diseases, such as banded sclerotial blight, rice blast, bakanae disease and the like, can be overcome. Therefore, the composite bactericide can be use for preventing and controlling most crop diseases in the paddy field.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a paddy field fungicide, in particular to a paddy field compound fungicide containing fuconazole, rice blastazol and flusilazole and an application thereof. Background technique [0002] Flutriafol, molecular formula C 16 h 13 f 2 N 3 O, chemical name: (RS)-2,4'-dichloro-a-(1H-1,2,4-triazole-1-methyl)benzylmethanol; [0003] Its chemical structural formula: [0004] . [0005] Triazole fungicide is a kind of triazole fungicide. The original drug is colorless crystal. It is stable in acid, alkali, heat and humid environment. It has broad-spectrum bactericidal activity and strong systemic absorption. It conducts to the top of the plant body. , has obvious therapeutic effect on diseases. It can prevent and control stem, leaf and ear diseases of cereal crops (mainly including rice, wheat, barley, rye, corn, etc.), soil-borne diseases (75mg / kg seed) and seed-borne dise...
