Problems solved by technology

Abnormal climatic conditions often lead to immaturity of sugarcane, resulting in severe loss of sugarcane yield, and chemical ripening agents are usually needed to help solve the problem at this time
[0003] Trifluxysulfuron-methyl is a sulfonylurea herbicide, mainly used to control broad-leaved weeds and sedge weeds, especially for the vicious weed Cyperus cyperus, but it is effective against grasses such as crabgrass and misngrass The weed control effect is poor, and its price is high, so its single use is limited to a certain extent

experiment example ）

[0025] Greenhouse potting method was used to determine the activity of trifluxysulfuron-methyl and trinexapac-ethyl compound on weeds (in this experiment, weed amaranth was taken as an example), and compared with trifluxysulfuron-methyl single agent and trifluxapac-ethyl single agent, the activity Fractions were treated with 0.1% Tween-80 in water.

[0026] Use a plastic nutrition pot with a diameter of 9cm, which contains air-dried surface soil collected from the farmland, keep the soil moist by supplying water from the bottom, sow weed seeds with full and uniform grains, cover the soil with 0.5cm, and place it in PWT-510 the next day Spray in the type spray tower (accurate spray area is 0.2m 2 , spray liquid 10mL, control spray 0.1% Tween-80 aqueous solution). 21 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 according to the Colby method. The result was th...

Embodiment 1）

[0032] The dosage form of the herbicidal composition of the present embodiment is a wettable powder, consisting of the following components by weight: 5 parts by weight of trifloxasulfuron-methyl, 20 parts by weight of trinexapac-ethyl, 3 parts by weight of Alkyl naphthalene sulfonate, 2 parts by weight of sodium salt of alkylnaphthalene sulfonate formaldehyde polycondensate as a dispersant, and 70 parts by weight of clay as a solid carrier.

[0033] Among them, the above-mentioned trifluxysulfuron-methyl and trinexapac-ethyl all come from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd.; the above-mentioned alkylnaphthalene sulfonate as a wetting agent comes from MorwetEFW of AkzoNobel; The sodium salt of alkylnaphthalene sulfonate formaldehyde polycondensate of the agent comes from Morwet D-425 of AkzoNobel Company; the clay used as the solid carrier comes from Mingguang Xingxin Mining Co., Ltd.

Abstract

The invention discloses a weeding composite for preventing and killing weeds in a sugarcane field. The active components of the weeding composite include trifloxysulfuron and trinexapac-ethyl which are combined based on the weight ratio of (1:0.01)-(1:100), and the weight of the active components accounts for 1-95% of the total weight of the weeding composite. The weeding composite can be wettable powder, or water dispersible granules, or a suspension agent, or an oil suspension agent, or a dry suspension agent, or powder, or granules, or missible oil, or emulsion in water, or microemulsion or suspension emulsion. The weeding composite has a remarkable weed preventing and killing effect on the sugarcane field, herbicidal activity is high, gramineae, cyperaceae and broadleaved weeds can be killed at a time, the synergism effect is remarkable, the weeding composite is safe to sugarcanes and can make sugarcanes become ripe before being harvested, the sugar degree of sugarcanes is higher, the yield increase effect is remarkable, and using cost can also be reduced.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicide composition for controlling weeds in sugarcane fields. Background technique [0002] Sugarcane is a very important crop in the field of agriculture, and its cultivation involves the production of sugar, industrial alcohol and fuel. Unusual weather conditions often lead to immaturity of sugarcane, which can cause severe loss of sugarcane yield, and chemical ripening agents are usually needed to help solve this problem. [0003] Trifluxysulfuron-methyl is a sulfonylurea herbicide, mainly used to control broad-leaved weeds and sedge weeds, especially for the vicious weed Cyperus cyperus, but it is effective against grasses such as crabgrass and misngrass The weed control effect is poor, and its price is high, so its single use is limited to a certain extent. Contents of the invention [0004] The object of the present invention is to solve the above problems and provide a herbicidal co...
