Embodiment Construction

[0015] Prepare 45% quinclorac·sclerotinia water dispersible granules.

[0016] Recipe:

[0017] Neat Sclerotinia 20%

[0018] Quinclorac 25%

[0019] NNO (dispersant) 8%

[0020] Sodium dodecylbenzenesulfonate (wetting agent) 1%

[0021] Starch (binder) 1%

[0022] Ammonium sulfate (disintegrant) 2%

[0023] Light calcium carbonate (filler) 43%

[0024] Weigh the material according to the above weight ratio, stir and mix evenly, and then pulverize and granulate to obtain the product. The preparations formulated according to the above ratio are 30 g / mu, 40 g / mu, and 50 g / mu. , Amaranthus retroflexus and other weeds are more than 90% effective, better than single use, see the following table 1, 2, 3.

Abstract

A biochemically synergistic herbicide composition relates to the technical field of agricultural production and comprises effective components, an assistant and a filler, and the effective components comprise Sclerotium rolfsii and quinclorac. The composition adopting Sclerotium rolfsii compounding has a high efficiency and a broad-spectrum weeding effect, has an excellent control effect on many broadleaf weeds and sedges of directly seeded drought rice, and weeds in fields externally invading by weeds, and has a better effect than respective use of Sclerotium rolfsii and quinclorac. The composition has the advantages of safety to crops, low cost and good control effect. Test proves that the herbicide composition has stable chemical properties, high efficiency and broad spectrum, and has an obvious synergistic effect on control objects.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to the technical field of herbicide preparation. 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 ...
