experiment example

[0027] Greenhouse potting method was used to measure the activity of sulfentrazone and clethodim compound on weeds (this experimental example took Cyperus cyperi as an example), and at the same time compared with sulfentrazone single agent and clethodim single agent, the active components Treat with 0.1% Tween-80 in water.

[0028] Use a plastic nutrient bowl with a diameter of 9 cm, which contains air-dried top soil collected from the farmland, and keep the soil moist by supplying water from the bottom, sow weed seeds with full and uniform grains, and cover the soil with 0.5 cm. There are 15 weeds in the pot. When Cyperus cyperi grows to the 2-leaf stage, spray in the PWT-510 spray tower (the precise spray area is 0.02m2, the spray liquid is 10mL, and the control sprays 0.1% Tween-80 aqueous solution) . Eighteen days after the treatment, the fresh weight of the aboveground part of the weeds was weighed, and the control effect of the fresh weight was calculated, and evaluated...

Embodiment 1

[0034] The dosage form of the herbicidal composition of the present embodiment is a wettable powder, consisting of the following components by weight: 25 parts by weight of sulfentrazone, 10 parts by weight of clethodim, 3 parts by weight of Alkyl naphthalene sulfonate, 2.5 parts by weight of lignosulfonate as a dispersant, 11.5 parts by weight of kaolin as a solid carrier, and 48 parts by weight of white carbon black as a solid carrier.

[0035] Among them, the above-mentioned sulfentrazone and clethodim all come from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd.; the above-mentioned alkylnaphthalene sulfonate as a wetting agent comes from Morwet EFW of Akzo Nobel; The lignosulfonate of the agent comes from Tensiofix IX of OMNIChem S.A.; the above-mentioned kaolin as a solid carrier comes from China Kaolin Co., Ltd.; the above-mentioned white carbon black as a solid carrier comes from Yangzhong Glass White Carbon Black Chemical Co., Ltd.

Abstract

The invention discloses a weeding composition for preventing and controlling weeds in a peanut field. The weeding composition comprises active ingredients including sulfentrazone and clethodim in the weight ratio of 0.01:1 to 100:1, and the weight of the active ingredients is 1%-95% of the total weight of the weeding composition. The weeding composition is in a form of wettable powder, water dispersible granule, oil suspending agent, dry suspending agent, granule, missible oil, emulsion in water, microemulsion or suspension emulsion. After the weeding composition is compounded, the herbicide controlling spectrum can be expanded, broadleaf weeds and grassy weeds can be removed, and the weeding composition has remarkable synergism. The weeding composition has a long optimum period of application, can be sprayed to soil before emergence, also can be sprayed to stems and leaves after emergence, has a low influence to the environment, is safe to current crops and afterreap crops, is safe to peanuts and is also suitable for various peanut varieties.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicide composition for controlling weeds in peanut fields. Background technique [0002] Peanut is an important source of edible oil and protein feed in my country. It has the characteristics of strong adaptability, wide application and high economic value. It is planted in most areas of my country. Peanuts have a long growth period and many types of weeds, which have a great impact on the yield of peanuts. [0003] Sulfentrazone (CAS accession number 122836-35-5) is a triazolinone herbicide that can control most broadleaf weeds, grass weeds and sedges. It has a good control effect on broad-leaved and sedge weeds such as retroflexus, amaranth, quinoa, datura, crabgrass, foxtail, cocklebur, goosegrass, and Cyperus cyperus. However, sulfentranacil kills weeds slowly and has a long residual period in the soil. [0004] Clethodim (CAS accession number is 99129-21-2) is a cyclohexenone herbicide...
