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] Clopyrazosulfuron-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 mansgrass 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 chlorpyrazosulfuron-methyl and trinexapac-ethyl compound on weeds (in this experiment, weed amaranth was taken as an example), and at the same time compared with chlorpyrazosulfuron-methyl and trinexapac-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 resu...

Embodiment 1）

[0032] The dosage form of the herbicidal composition of the present embodiment is a wettable powder, which is composed of the following components by weight: 5 parts by weight of chlorpyrazosulfuron-methyl, 15 parts by weight of trinexapac-ethyl, 3 parts by weight of Alkylnaphthalene sulfonate, 2 parts by weight of alkylnaphthalene sulfonate formaldehyde polycondensate sodium salt as a dispersant, and 75 parts by weight of kaolin as a solid carrier.

[0033] Among them, the above-mentioned chlorpyrazosulfuron-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 sulfonic acid formaldehyde polycondensate of the agent is derived from Morwet D-425 of AkzoNobel; the above-mentioned kaolin as a solid carrier is derived from China Kaolin Co., Ltd.

[0034] The preparation method is ...

Embodiment 2～ Embodiment 5）

[0036] The preparation method of each example is the same as Example 1, the difference lies in the parts by weight of each component, see Table 2 for details.

Abstract

The invention discloses a herbicidal composition used for preventing and controlling weeds in sugarcane fields. Active ingredients of the herbicidal composition include halosulfuron-methyl and trinexapac-ethyl in a weight ratio of (1 to 0.01)-(1 to 100) and account for 1-95wt% of the total herbicidal composition. The dosage form of the herbicidal composition is wettable powder, a water dispersible granule, a suspension, an oil suspension, a dry suspension, powder, a granule, emulsifiable concentrate, emulsion in water, microemulsion or suspension emulsion. The herbicidal composition has obvious prevention and control effects on the weeds in sugarcane fields, has high herbicidal activity, can be used for preventing and controlling gramineae, cyperaceae and broadleaf weeds once, has obvious synergistic effects, is safe to sugarcanes, can enable the sugarcanes to ripen before harvest and the sugar degrees of the sugarcanes to be higher, has obvious yield increase effects and can conduce to reducing the use cost.

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] Clopyrazosulfuron-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 mansgrass 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 c...
