Abstract
A composite herbicide series for graninaceous and latifolious grasses in before-seedling stage in soybean, corn and peanut field is prepared from chemical sulfonylurea and amide herbicides, carrier, surfactant and synergist through pneumatic pulverizing and mixing to obtain wettable powder. Its advantages include high safety and moderate residual period.
Description
Technical field: the present invention relates to a kind of compound chemical weed killer herbicide, especially a kind of soybean field, corn field, peanut Tian Miaoqian weeding composition series.
Background technology: corn, soybean, peanut are important oil plant of China and economic crops, its long-term cultivated area reaches several hundred million mu, quickening along with the accession to WTO process, China's agricultural planting structure also will be adjusted thereupon, the cultivated area of corn, soybean, peanut will continue to enlarge, particularly the Northeast will be helped by national policy.Yet average out to about 20% can have no harvest when serious all because of being subjected to the harm underproduction of weeds every year for corn, soybean, peanut yield.Developed country's corn field, soybean field, that the peanut field weed is prevented and treated level is higher, and China is then lower, and the method for control has before the seedling after the closed soil and seedling cauline leaf handle two kinds.According to the harm situation of China's corn field, soybean field, peanut field weed, closed soil treatment is main before the Ying Yimiao, and cauline leaf is treated to auxilliary behind the seedling.
The medicament of soil treatment mainly contains before the present domestic seedling: drag-line, standing grain anti-this, all that, Probiotics, trefanocide, Wei Nong, metribuzin, 24-D butyl ester, clomazone, the general top grade of executing, its use is single agent, or prevents and kill off grassy weed, or prevents and kill off broad leaved weed.Because use for many years, weeds are developed immunity to drugs, cause consumption to increase year by year, make simultaneously and do the recessive poisoning of deposits yields and the underproduction, and dangerous to succession crop.As use Pu Shite, and could plant corn behind 9 first quarter moons, 40 months ability kind beets could be planted paddy rice after a year and a half; Adjust pattern of farming to the peasant like this and bring great inconvenience; Simultaneously, along with the use of chemical herbicide, variation has taken place in its weed control, and is former in grassy weed as south, now developed into the coexistence of grass family and broad leaved weed; The north is former in broad leaved weed, now also developed into the coexistence of grass family and broad leaved weed, so just press for and to prevent and kill off grassy weed, can prevent broad leaved weed again and not influence the weed killer herbicide new varieties that succession crop is planted, yet this at home weed killer herbicide still belongs to blank.
Summary of the invention:
Technical problem to be solved by this invention is: provide a kind of and can prevent and kill off grassy weed, can prevent and kill off broad leaved weed again and not influence soybean field, corn field, the peanut field composition series of herbicides for before-seedling stage that succession crop is planted.
Technical scheme of the present invention is: with sulfonylurea and amides compound weed killer herbicide is effective ingredient, adds an amount of carrier, surfactant, synergist through comminution by gas stream, mixes, and is made into wetting powder.
Described sulfonyl urea compound weed killer herbicide is a thifensulfuronmethyl; Described amides compound weed killer herbicide is alachlor, Acetochlor, isopropyl methoxalamine, propisochlor.
The quality percentage composition of described thifensulfuronmethyl is: 0.1-25, the quality percentage composition of alachlor or Acetochlor or isopropyl methoxalamine or propisochlor is: 10-70.
Described carrier is kaolin, white carbon black, diatomite, potter's clay, bentonite, precipitated calcium carbonate, clay, atlapulgite, talcum powder, chalky soil.
Described surfactant is the compound of anionic, nonionic and them, can be NNO BX LS, lignosulfonates, carboxymethyl cellulose salt class, alkylsulfonate, fatty alcohol sulfonate, alkylphenol polyoxyethylene.
Described synergist is azone, permeable synergistic agent, N-ethanol based dodecylphenyl sodium sulfonate, bleeding agent CN.
Composition series weed killer herbicide of the present invention, field control effectiveness test for many years by Anhui, Liaoning, the Inner Mongol, Henan and other places shows, be used to prevent and kill off corn field, soybean field, the multiple grassy weed of peanut Tanaka and broad leaved weed, as barnyard grass grass, green foxtail, wild oat, setaria glauca, lady's-grass, eleusine indica, lamb's-quarters, Amaranthus retroflexus, dayflower, Siberian cocklebur, Sheep's-parsley, Tong fiber crops, water sour jujube pin, corn-bind, wolf tail grass etc.Have significant herbicidal effect, obvious synergistic effect and wide spectrum kill careless function, and the weeds harm in the crop whole growing, saving of work and time, increasing both production and income can be effectively controlled in a dispenser; Its consumption is lower than single agent consumption, and therefore, the longevity of residure is moderate, to plant height safety, succession crop is had no effect, is the improved seeds of corn field, soybean field, the seedling pre-treatment of peanut field.
