Abstract
The invention discloses a pesticide composite containing bispyribac-sodium and penoxsulam and an application thereof. The pesticide composite comprises effective components including bispyribac-sodium and penoxsulam, the weight ratio of the bispyribac-sodium to the penoxsulam is from 10:1 to 1:10, and the total weight of the bispyribac-sodium and the penoxsulam accounts for 1-40 percent of the weight of the pesticide composite. The pesticide composite is suitable for preventing and controlling annual weeds in paddy fields. The pesticide composite has a remarkable synergistic effect on control the efficiency of annual weeds in paddy fields compared with a mono-agent and has the advantages of reducing the dosage of the pesticide and the dosing cost, prolonging the service life of the pesticide and reducing the negative influence of the pesticide on the ecological environment.
Description
Technical field
The present invention relates to composition pesticide, particularly a kind of composition pesticide and application thereof that contains two careless ethers and penoxsuam is take two careless ethers and penoxsuam as active ingredient, for preventing and kill off farmland weed, is particularly useful for preventing and kill off the paddy field annual weed.
Background technology
Two careless ethers, English common name bispyribac-sodium, the genus benzoic acid derivative, it absorbs by the root leaf and suppresses sour synthesizing of vinegar milk and hindered aminoacid biosynthesis side chain.Be selective herbicide, can effectively prevent and kill off barnyard grass in paddy field and other grassy weeds, double most of broad leaved weeds, some sedge weeds and the resistance barnyard grass controlled.
Penoxsuam, English common name penoxsulam, the sulfanilamide (SN) carbamide herbicides, be translocated herbicide, through cauline leaf, young shoot and Root Absorption, conduct to meristematic tissue by xylem and phloem, suppress plant strain growth, make the growing point chlorosis, the rear 7 ~ 14d terminal bud of processing reddens, necrosis, and 2 ~ 4 all plant are dead.Penoxsuam is strong inhibitor of acetolactate synthetase, and medicament presents slower, needs the certain hour weeds just dead gradually.Can be used for preventing and kill off barnyard grass in paddy field and annual sedge weed, and effective to multiple broad leaved weed.
Being mixed of different pesticide species is the common methods of preventing and kill off agriculture resistance disease pest and weed.By the formulation of pesticide screening, filter out rational prescription, but the actual preventive effect of Effective Raise reduces dosage, reduces cost, delays the drug-fast generation of disease pest and weed, be the important means that agricultural synthesis is administered.The inventor conducts in-depth research the prescription screening of two careless ethers and penoxsuam, find that two careless ethers and penoxsuam are mixed, in certain mixed ratio scope weeds there are certain synergy or summation action, can effectively prevent and kill off the paddy field annual weed.After further study, finished the present invention.
Summary of the invention
The object of the invention is to solve in the prior art develop immunity to drugs problem and promote drug effect of farmland weed, a kind of efficient, low toxicity, environmental protection are provided, be conducive to the two careless ether of the farmland weed comprehensive regulation and the composition pesticide of penoxsuam.
Another object of the present invention is be used to preventing and kill off farmland weed, being particularly useful for preventing and kill off paddy field annual weed etc.
Technical scheme: the present invention is take two careless ethers and penoxsuam as active ingredient, the ratio of weight and number of two careless ethers and penoxsuam is 10:1～1:10, two careless ethers and the percentage by weight of penoxsuam weight summation in composition pesticide are 1%～40%, and all the other are to allow in the pesticidal preparations to use and the acceptable auxiliary element.
The present invention is prepared into known method and is fit to upper any one formulation used of agricultural, such as environment amenable formulations such as oil-suspending agent, wetting powder, water dispersible granules, effervescent tablet, aqueous suspension agents.
The auxiliary agent that the present invention uses comprises that solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, defoamer, antifreezing agent, packing agent etc. are of value to active ingredient stablizes and bring into play drug effect in preparation known substance, all be various compositions commonly used in the pesticidal preparations or that permission is used, concrete composition and consumption require to pass through test according to prescription and determine.
Product described in the invention can finished product preparation form provide, namely each material mixes in the composition, the form that the composition of composition also can single dose provides, and directly mixes in tank or bucket before the use, then is diluted to needed concentration.Frequency of administration of the present invention and amount of application change with weather conditions and weeds situation, can reach the purpose of preventing and kill off by using suitable dosage.
The present composition is applicable to prevent and kill off farmland weed, is particularly useful for the paddy field annual weed.
Compared with prior art, the invention has the advantages that.
1, two kinds of active ingredients are mixed and have obvious synergistic effect, have improved preventive effect, have reduced the agricultural chemicals usage amount, have reduced cost and to the pollution of environment.
2, the combination of two kinds of active ingredients has enlarged herbicidal spectrum, and two kinds of active ingredient mechanism of action are different simultaneously, can overcome the shortcoming that single dose easily produces resistance, prolong the service life of medicament.The application of composition can delay or overcome the drug-fast generation of rice weed, is conducive to agricultural synthesis and administers.Enlarged and prevented and kill off spectrum.
3, composition pesticide provided by the invention is to crop safety.
Embodiment
The present invention describes by following specific embodiment, but the invention is not restricted to following specific embodiment.In these embodiments, unless otherwise indicated, all percentages all are weight percentage.
Biologicall test embodiment.
Be mixed to the synergy of weeds for further understanding two careless ethers and penoxsuam, the inventor is mixed to two careless ethers and penoxsuam and has carried out formulation screening test.
Test material: chickweed [
Stellaria media(L.) Cyrillus] (field is collected seed and is preserved).Barnyard grass [
Echinochloa crusgalli(L.) Beaw Setaria] (field is collected seed and is preserved).
Test apparatus; Controlled illumination box; The accurate laboratory of POTTER spray tower; Electronic balance (sensibility reciprocal 0.1mg); Micropipette rifle etc.
Test method; Take by weighing first 93% pair of former medicine of careless ether of certain mass, the former medicine of 98% penoxsuam adds the Tween 80 aqueous solution dilution that acetone fully dissolves rear usefulness 0.1%, is mixed with respectively the single dose mother liquor, according to the purpose that is mixed serial proportioning is set, each proportioning arranges 5～7 concentration gradients.Select representative susceptible weeds seed according to single dose herbicide spectrum, be cultured to 2 leaves, 1 stamen for subsequent use.After the weeds cauline leaf of selecting numbering processed, be placed in the illumination box incubated at room temperature 5 days, calculate preventive effect (fresh weight), then with method of least squares calculate suppress in dense EC
50(95% confidence limit) calculates co-toxicity coefficient (CTC) with the abundant method of Sun Yun again.
Co-toxicity coefficient (CTC) 〉=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80＜co-toxicity coefficient (CTC)＜120 shows as summation action.
Measurement result shows, two careless ethers and penoxsuam are between 10:1～1:10 at ratio of weight and number, and co-toxicity coefficient has obvious synergistic effect more than 120.
The two careless ethers of the different proportionings of table 1 and penoxsuam are measured the synergy of barnyard grass.
The two careless ethers of the different proportionings of table 2 and penoxsuam are measured the synergy of chickweed.
