example 1

[0033] The following specific examples illustrate the present invention in detail, but the present invention is by no means limited to these examples. The percentages in the proportioning ratio of all preparations are percentages by weight. Preparation of Composition and Biological Activity Example 1, Preparation of Wettable Powder

[0034] According to the requirements of the formula, the original drug, various additives and fillers are fully mixed, and the processed product is obtained after being pulverized by an ultra-fine pulverizer. Such as example 1~13 formula

[0035] Example 1 (42% wettable powder)

[0036] Sulcotrione 2%, Atrazine 40%, Sodium Lauryl Sulfate 1.5%, Alkyl Naphthalene Sulfonate Formaldehyde Condensate 6%, Sodium Lignosulfonate 5%, Light Calcium Carbonate supplemented to 100%.

example 2

[0037] Example 2 (40% wettable powder)

[0038] Sulcotrione 5%, Atrazine 35%, Sodium Lauryl Sulfate 1.5%, Carboxymethyl Cellulose 1%, Sodium Lignosulfonate 5%, Naphtholsulfonic Acid Formaldehyde Condensate Sodium Salt 5%, Light calcium carbonate tops up to 100%.

example 3

Abstract

The present invention relates to a weedicide composition. It contains sulcotrione and at least one tripyridine weedicide. The weight portion ratio of sulcotrione and tripyridine weedicide is 1:100 to100:1, and the weight percentage content of the active component in the composition is 0.5-95%, and the described tripyridine weedicide is: atrazine, simazine, metribuzin, cyanazine, prometryn and ametryn, etc. Said weedicide composition has obvious synergistic action, can be used for controlling gramineous weeds and latifolious weeds.

Description

technical field [0001] The present invention relates to a herbicide composition containing a herbicide substance, in particular to a herbicide composition containing sulcotrione [chemical name: 2-(2-chloro-4-carboxamide benzoyl) cyclohexane-1,3-dione] Preparation and application of composition with triazine herbicides. Background technique [0002] At present, the herbicides used in cornfields in my country mainly include A-B mixture (atrazine + acetochlor) applied before seedlings, 2,4-D butyl ester, dicamba, bromoxynil, Yunongle, etc. applied after seedlings. . Because atrazine has a long residual effect in the soil, it is not conducive to crop rotation and stubble, which not only affects the subsequent planting of cruciferous vegetables, but also causes phytotoxicity to the subsequent planting of wheat and soybeans, and the herbicide used in soil treatment The herbicide effect is greatly affected by soil moisture, and the drug effect is poor or even ineffective during dr...
