AI Technical Summary

Problems solved by technology

Compound (A) florasulam has a wide herbicidal spectrum, and can control most broad-leaved weeds in wheat fields, including hard-to-control weeds such as pigtails and barley, and has the effect on the most difficult-to-control varnish in wheat fields. Very good inhibitory effect, but has little control effect on gramineous weeds such as sagegrass, wild oats, false oats, brachiaria, crabgrass, barnyardgrass, stonegrass, and false sorghum
The compound (B) clodinafop-propargyl has excellent control effect on wild oats and arpeggios in wheat fields, but has no control effect on broad-leaved weeds
At the same time, there is no report on the mixing of florasulam and clodinafop-propargyl in an appropriate ratio to control weeds in wheat fields

Embodiment 1

[0029] Example 1: Preparation of wettable powder.

[0030] 3% active ingredient (A) with 17% active ingredient (B), 2% sodium lauryl sulfate as wetting agent, 5% NNO as dispersant, 5% lignin as dispersant Calcium sulfonate, 20% white carbon black and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Embodiment 2

[0031] Embodiment 2: the preparation of suspending agent.

[0032] 2% active ingredient (A) and 23% active ingredient (B), 6% Nongru No. 33 as wetting and dispersing agent, 5% ethylene glycol as antifreeze, 0.2% as thickener Grinding xanthan gum and water in a sand mill with an appropriate amount of glass beads to obtain a suspending agent.

Embodiment 3

[0033] Example 3: Preparation of water-dispersible granules.

[0034] 4% active ingredient (A) with 56% active ingredient (B), 5% carboxylate as wetting agent, 5% NNO as dispersant, 5% lignosulfonic acid as dispersant Calcium and other inert fillers are thoroughly mixed together and ultrafinely pulverized, then an appropriate amount of water and binder is added to the mixture, and the water-dispersible granules can be obtained after fluidized bed granulation or extrusion granulation and drying.

Abstract

The invention relates to a weeding composition containing florasulam and clodinafop-propargyl, a preparation method and use thereof, wherein, the weeding composition is composed of a compound (A)-the florasulam and a compound (B)-the clodinafop-propargyl. The weeding composition of the invention obtained based on a proper mixing ratio can be processed into conventional formulations of pesticide such as wettable powder, suspension concentrate, water dispersible granules and the like by adopting a modern pesticide preparation processing technology, and the weeding composition can be used for controlling gramineous weeds and broadleaf weeds in fields such as cleavers, lithospermum arvense, alisma rhizome, common vetch, chickweed, capsella, silene jenisseensis willd, chorispora tenella, pennsylvania bittercress, stellaria alsine grimm, polygonum convolvulus, salvia alopecurus aequalis, wild oat, animated oat, brachiaria, crabgrass, barnyard grass, goosegrass, Italian ryegrass, goosefoot, common annual bluegrass, setaria glauca, green bristlegrass herb, Johnson grass and the like. The weeding composition has obvious control effect compared with the mode of only using the compound (A) or the compound (B) and significantly reduces application dosage of each active substance; and the weeding composition has great ecological and environmental protection significance.

Description

technical field [0001] The present invention relates to a herbicidal composition with improved properties, in particular to a herbicidal composition containing florasulam and clodinafop-propargyl and its use. Background technique [0002] The common name of compound (A) is florasulam, and its chemical name is 2,6'-difluoro-5-ethoxy-8-fluoro-[1,2,4]-triazole-[1,5 -c] pyrimidine-2-sulfonanilide. [0003] The English name of florasulam: florasulam. CA Registration Number: 145701-23-1. The development unit is Dow AgroSciences Corporation of the United States, which obtained the Chinese patent in May 1989, and the patent publication numbers are CN1030606C (3) and CN1037605C (2). [0004] Flusulam is a super-efficient herbicide of sulfonamides, which is used to control broad-leaved weeds in wheat fields. It has a wide herbicidal spectrum and can control most of the broad-leaved weeds in wheat fields, including the difficult-to-control weeds such as pig scorpion and Maijiagong,...
