Problems solved by technology

The plant height can reach 20-80cm, and the reproductive ability is strong. With the use of pesticides, plants that were originally sensitive to glufosinate, glyphosate, tribenuron-methyl, and bensulfuron-methyl have gradually developed into glufosinate-ammonium, glyphosate-resistant plants. As well as sulfonylurea biotype Artemisia indica, which brings great troubles to the weeding work of non-cultivated land, orchards, and roads

Embodiment 1

[0026] Glufosinate-ammonium 20.3%, Flusulam 0.1%, Sodium a-olefin sulfonate (AOS) 1%, Sodium lignosulfonate (REAX82P) 5%, Precipitated silica 10%, Pregelatinized starch 3%, light calcium balance. Mix the above-mentioned components uniformly according to the stated proportions, and perform jet crushing so that the average particle size of the material is less than 5 μm, thereby obtaining 20.4% glufosinate-ammonium · florasulam wettable powder.

Embodiment 2

[0028] Glufosinate-ammonium 20.3%, Flusulam 0.1%, Sodium Lauryl Sulfate (K-12) 2%, Methylnaphthalene Sulfonate Sodium Formaldehyde Condensate (MF) 5%, Precipitated Silica 5% , sodium carboxymethyl cellulose 2%, corn starch balance. Mix the above-mentioned components uniformly according to the stated proportions, and perform jet crushing so that the average particle size of the material is less than 5 μm, thereby obtaining 20.4% glufosinate-ammonium · florasulam wettable powder.

Embodiment 3

[0030] Glufosinate-ammonium 20.3%, florasulam 0.1%, fatty alcohol polyoxyethylene ether (AEO-7) 7%, styrylphenol polyoxyethylene ether phosphate (601P) 6%, precipitated silica 1 %, xanthan gum 0.15%, silicone defoamer 0.2%, ethylene glycol 5%, water balance. Mix glufosinate-ammonium, florasulam, AEO-7, 601P, white carbon black, silicone defoamer, ethylene glycol, and some water evenly in proportion, and grind them with a sand mill to make the average particle size of the material If the thickness is less than 3 μm, detect the content of glufosinate-ammonium and florasulam, add xanthan gum and the rest of water, and mix evenly again to obtain 20.4% glufosinate-ammonium-flusulam suspension concentrate.

Abstract

The invention discloses compound herbicide composition. The compound herbicide composition comprises effective components including glufosinate and florasulam in the weight ratio being (100-350) : (0.25-2.5). The compound herbicide composition belongs to a sterilant herbicide and can be used for controlling weeds in the uncultivated area, orchards, farmland and other areas. After mixed use of glufosinate and florasulam, the herbicide composition has a remarkable synergistic interaction function on descurainia Sophia and other broadleaf weeds and has the advantages of stable weeding effect at the low temperature, wide weed control spectrum and the like while compared with a single glufosinate agent. The use dosage of a pesticide can be effectively reduced, the adverse effect of the pesticide on the ecological environment is reduced, and the compound herbicide composition has a great significance in resistance comprehensive treatment of weeds and has huge economic benefits and social benefits.

Description

technical field [0001] The present invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with glufosinate-ammonium and florasulam as active ingredients, which is mainly used for preventing weeds in areas such as non-cultivated land, orchard and farmland . Background technique [0002] Glufosinate is an organophosphorus non-selective contact herbicide targeting glutamine synthetase (GS). It is mainly used to control annual or perennial dicotyledonous and monocotyledonous weeds in orchards, vineyards, non-cultivated land, etc., but there are problems such as reduced efficacy at low temperature and poor control effect on winter broad-leaved weeds. [0003] Florasulam (florasulam) is an amide super-efficient herbicide, mainly used for the control of broad-leaved weeds in wheat fields, resistant broad-leaved weeds Artemisia spp. and other weeds have good control effects, and can still maintain good control e...
