Abstract
The invention discloses compounding herbicide for a cotton field, which relates to the technical field of pesticide and consists of two kinds of active ingredients: trifloxysulfuron and tefuryl, wherein the weight ratio of the trifloxysulfuron to the tefuryl is 1/(0.5 to 1.5), and preferably, the mass percentage of the trifloxysulfuron and the tefuryl is 4 to 85 percent of the compounding herbicide. The compounding herbicide can be used for preventing and killing cotton field annual broadleaf weed and can also be used for preventing and killing graminaccae weed and nutgrass flatsedge, the weed killing effect is obvious, the obvious synergia effect is realized, in addition, the weed in the whole growth period of the crops can be prevented and killed through once herbicide application, no influence is caused on the later stubble of crops, and the herbicide belongs to the ideal herbicide.
Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of complex weedicide that is used for the cotton field.
Background technology
Cotton is most important economic crops of China still not, also are very valuable strategic materials.About 7,592 ten thousand mu of the sowing areas of Cotton in China.
Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.At present, the weeding of domestic cotton field mainly is weeding before the seedling.
Trifloxysulfuron is to belong to sulfonylurea herbicide; Can be absorbed by the root of weeds, stem, leaf after the dispenser; Can in plant corpus, conduct downwards with upwards; Through suppressing the activity of acetolactate synthestase (ALS), thereby influence the biosynthesis of branched-chain amino acid (as: leucine, isoleucine, valine etc.).Show as growing point necrosis, vein chlorosis behind the hazard of plant, plant growing receives severe inhibition, dwarfing, and final complete stool is withered.
Trifloxysulfuron mainly is because the difference of katabolism to the selectivity of weeds and crop.It can be the non-activity material by rapid metabolism in the cotton body, thereby crop plant is escaped injury.
Be mainly used in and prevent and kill off broad leaved weed and sedge weed.On endive (Sonchus), quinoa (Chenopodium album), a small quinoa, Chenopodium glaucum, purslane, redroot pigweed, Amaranthus lividus, green ear Amaranthus, Cephalanoplos, gill bud fruit, ragweed, Bidens, big Alondra, water, peanuts, wild rape, field bindweed, playing bowl of flowers, fruit, sweet wine intestine (Eclipta), Sesbania, Ageratum, Yu Mang Ju, Brachiaria, Euphorbia , vat wood sorrel (sour Mimi) and other broadleaf weeds with good control effect; pair of purple nutsedge (Spartina grass) have effects; against crabgrass, barnyard drought, goosegrass, foxtail, sorghum and other cereal weed control effect is poor.
QuizalofopPtefuryl is to be transferred in the plant corpus from Foliage Absorption, in xylem and phloem, moves, and in meristem, accumulates. be used for preventing and kill off the annual and perennial grassy weed on potato, flax, rape, soybean, beet, cotton and Peas ground.
Both are composite can to have complementary advantages, and increases the preventive effect to weeds, saving of work and time.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can prevent and kill off grassy weed, can prevent and kill off broad leaved weed and nutgrass flatsedge again, and respond well complex weedicide.。
In order to realize the foregoing invention purpose, the present invention provides following technical scheme:
A kind of complex weedicide comprises trifloxysulfuron and quizalofopPtefuryl, and the weight ratio of trifloxysulfuron and quizalofopPtefuryl is 1: 0.50-1: 1.5.
As preferably, the weight ratio of trifloxysulfuron and quizalofopPtefuryl is 3 in the complex weedicide according to the invention: 2-7: 10.
More preferably, the weight ratio of trifloxysulfuron and quizalofopPtefuryl is 1: 1 in the complex weedicide according to the invention.
On the other hand, the present invention provides that the quality percentage composition of trifloxysulfuron and quizalofopPtefuryl is 4～85% of a said complex weedicide in the biological said complex weedicide.
As preferably, in the complex weedicide according to the invention, two kinds of active components of trifloxysulfuron and quizalofopPtefuryl according to above-mentioned weight ratio composite after, process the formulations of pesticide such as oil-suspending agent, wetting powder or water dispersible granules.
Synergy after using with the co-toxicity coefficient method evaluation of Sun Yunpei; The result shows that trifloxysulfuron, quizalofopPtefuryl are in 1: the composite co-toxicity coefficient of 0.5-1.5 ratio is obviously greater than 120; Reach remarkable synergistic effect; Explain that trifloxysulfuron, quizalofopPtefuryl are in 1: the 0.5-1.5 ratio is mixed comparatively suitable, and annual single broadleaf weed and nutgrass flatsedge are had significant synergies.
Safety determination test to cotton shows that the composite cauline leaf of trifloxysulfuron quizalofopPtefuryl is handled, and suppresses the ED of cotton growth 10%
10=633.5774, the ED of inhibition weed growth 90%
90=147.8637, selectivity factor is 633.5774/147.8637=4.28＞2, thinks that this medicament has obvious selectivity, and the trifloxysulfuron quizalofopPtefuryl has good control efficiency to weeds.
Complex weedicide according to the invention shows that through the field control effectiveness test in 2 years in 2～4 leaf phases of cotton, weeds 2-5 leaf does not wait the phase, and cotton does not see symptom of chemical damage from the dispenser to the maturing stage, to cotton safety.The preventive effect of weeds reached more than 80% in 10 days, reached more than 90% in 30 days, along with the increase of dosage; Preventive effect obviously strengthens, and a dispenser can be controlled the weeds in the crop whole growth phase, and not only herbicidal effect is remarkable; And environmentally friendly, second stubble crop there is not influence.
Compared with prior art, complex weedicide according to the invention can be prevented and kill off grassy weed, can prevent and kill off broad leaved weed and nutgrass flatsedge again, to cotton safety, and succession crop is not had influence, has a good application prospect.
Embodiment
