Efficient weeding medical fertilizer

Abstract

The invention relates to an efficient weeding medical fertilizer. Active ingredients consist of urea, monoamine phosphate, potassium chloride, sodium selenate and 50% cyhalofop-butyl-sclerotium rolfsii water dispersible granules. The efficient weeding medical fertilizer has a good weeding effect: the 50% cyhalofop-butyl-sclerotium rolfsii water dispersible granules have an efficient broad-spectrumweeding effect, have an excellent control effect on various broadleaf weeds, sedge and weeds from places which are invaded by foreign weeds in dry direct seeding rice, and exceed the use of two single-dose varieties of sclerotium rolfsii and quinclorac. The efficient weeding medical fertilizer has the advantages of safety to crops, low cost and good control effect. Tests show that the 50% cyhalofop-butyl-sclerotium rolfsii water dispersible granules have stable chemical properties, efficient broad spectrum, and an obvious synergistic effect on controlled objects.

Description

technical field [0001] The invention relates to the field of agricultural production technology fertilizers, in particular to the technical field of preparation of herbicide fertilizers. Background technique [0002] With the popularization and application of rice light cultivation technology, how to scientifically and accurately control weeds in rice fields and fertilize scientifically has become an important part of field management during rice growth. The annual economic loss caused by weed hazards in my country is more than 100 billion. The current means of controlling weeds mainly rely on the use of 100,000 tons of chemical herbicides because there are no biological herbicide products, and the area of ​​chemical herbicide use exceeds 1 billion mu. . As a result, a large number of chemical weeding has caused problems such as soil and water pollution, weed resistance, crop damage, and pesticide residues in agricultural products. Weed resistance alone leads to an annual i...
