Description

A kind of sugarcane field herbicides special and preparation method thereof

Technical field

The present invention relates to a kind of weed killer herbicide and preparation method thereof, be specifically related to a kind of sugarcane field herbicides special and preparation method thereof, belong to preparation technique of pesticide field.

Background technology

Sugarcane, (formal name used at school: Saccharumofficinarum) saccharum, perennial tall and big solid draft.The sturdy prosperity of root-like stock.Stalk height 3-5(-6) rice.The southern torrid areas such as TaiWan, China, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan are extensively planted.Sugarcane is applicable to planting in fertile soil, the place that sunny, summer in the winter temperature difference is large.Sugarcane is temperate zone and tropical crops, is the raw material manufacturing sucrose, and can refines ethanol as energy substitution product.The whole world has more than 100 country to produce sugarcane, and maximum sugarcane production state is Brazil, India and China.

The main product sugarcane district of China, is mainly distributed in the tropical and subtropical region on the south north latitude 24 °, comprises 12, south province, the autonomous regions such as Guangdong, Taiwan, Guangxi, Fujian, Sichuan, Yunnan, Jiangxi, Guizhou, Hunan, Zhejiang, Hubei, Hainan.Since 20th century the mid-80s, the sucrose producing region of China is rapidly to the transfer of the west area such as Guangxi, Yunnan, and to Guangxi in 1999, the sucrose yield of the Yunnan two province 70.6%(that accounted for the whole nation do not comprise Taiwan Province).Along with the development of production technology, also there is dispersed greenhouse gardening (as Henan, Shandong, the ground such as Hebei) in the central plain area of China's Mainland.

Sugarcane is before envelope row, and weeds easily grow, and consumes nutrient and hides sugarcane seedling, so will carry out the weeding of sugarcane field in time.Generally in conjunction with cultivation and banking, carry out with manual operations.

CN201310403193.0 discloses a kind of sugarcane field herbicide synergistic combination.Oxyfluorfen, halosulfuronmethyl, Acetochlor are used alone as traditional weed killer herbicide, but all can not effectively act on and close down the weeds such as the rhizome of nutgrass flatsedge.This sugarcane field herbicide synergistic combination comprises active ingredient and auxiliary material, wherein active ingredient has following component to form according to shown weight ratio configuration, Oxyfluorfen 1.5 ~ 45, halosulfuronmethyl 1.0 ~ 20, Acetochlor 6 ~ 60, it is also closed down in the lump to the malignant weeds such as corymb woodsorrel herb or root, Rottboellia exaltata, junglerice and other weeds in sugarcane field common, at sugarcane field a drug, herbicidal effect can be reached.

CN201510056372.0 discloses a kind of sugarcane field weed killer herbicide for low-gallonage spraying, the formulation of this weed killer herbicide is suspending agent, farm chemical ingredients is made up of ametryn and weed killer herbicide II, and weed killer herbicide II is that methoxone, diuron, hexazinone, terbufos benzthiazuron, halosulfuronmethyl, trifluoro heavy stone used as an anchor sulphur are grand, one or both combinations in mesotrione or benzene azoles humulone.In this invention, ametryn and weed killer herbicide II are prevented and kill off sugarcane field weeds with certain proportion mixture and are had synergistic effect, and control efficiency is apparently higher than each single dose; The weed killer herbicide of this 1 invention is prepared into suspending agent simultaneously and can be used for low-gallonage spraying, significantly reduce drift, improve the composition wetting and spreading performance of agricultural chemicals, also there is saving of labor, water-saving, province's medicine, efficient, holding effect, environmental protection, advantage that cost is low.

CN201210172360.0 discloses a kind of herbicidal composition of dripping containing ethoxysulfuron and 2,4-and production method thereof, its active ingredient: ethoxysulfuron percentage by weight is 0.1% ~ 10%, 2,4-drip percentage by weight 1% ~ 40%, and all the other are auxiliary agent.This herbicidal composition effectively can dispose sedge weed in sugarcane field and broad leaved weed, the especially rhizome of nutgrass flatsedge and window-box oxalis, has good weeding ability, and to sugarcane safety, with low cost.

But the preparation cost of above patent is relative still higher, herbicidal effect is not also very good, applies and also there is certain difficulty.
