Embodiment 1

[0011] Example 1: 45% Sclerotinia sclerotium · bensulfuron-methyl water-dispersible granules

[0012] Neat Sclerotinia 40%

[0013] Bensulfuron-methyl 5%

[0014] NNO (dispersant) 8%

[0015] Sodium dodecylbenzenesulfonate (wetting agent) 1%

[0016] Starch (binder) 1%

[0017] Ammonium sulfate (disintegrant) 2%

[0018] Light calcium carbonate (filler) 43%

[0019] The material is weighed according to the above weight ratio, stirred and mixed evenly, and then crushed and granulated to obtain the product.

[0020] The preparation formulated with the above ratio was used to control weeds such as crabgrass, barnyardgrass, and amaranthus in cornfields at the application rate of 30 g / mu, 40 g / mu, and 50 g / mu. The results showed that: the control effect More than 90%, better than single use.

Abstract

The invention provides a novel herbicide, relates to the technical field of pesticide production. Active components of the herbicide comprise sclerotinia rolfsii sacc and bensulfuron methyl, and water dispersible granules are the product preparation of the herbicide. The herbicide comprises the following raw materials in percentage by weight: 1-40 percent of sclerotinia rolfsii sacc, 1-25 percent of bensulfuron methyl, 2-25 percent of auxiliaries, and 10-96 percent of a filler. The novel herbicide shows efficient and broad-spectrum weeding performance, is mainly applied to prevention and removal of a plurality of broadleaf weeds and nutgrass flatsedge in dry direct seeding rice, and does not influence the crops.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to the production technology of herbicides. Background technique [0002] 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 increase of 10,000 tons of herbicide use, which intensifies the pressure of environmental pollution and reduces the weeding effect. Weed control in rice production is the most critical element in various light cultivation techniques. The anhydrous cover and alternating wet and ...
