Abstract
The invention discloses a pesticide composition comprising butafenacil and a phenoxycarboxylic acid type herbicide. The active components of the pesticide are butafenacil and the phenoxycarboxylic acid type herbicide. The weight ratio of butafenacil to the phenoxycarboxylic acid type herbicide in the composition is 5:1-1:30. The total weight of butafenacil and the phenoxycarboxylic acid type herbicide accounts for 0.1-90% in the composition by weight, and the balance is pesticide auxiliary agents. The herbicidal composition provided by the invention is used for controlling and removing weeds in orchards, non-cultivated lands, vine crop fields, cotton fields, and the like. The weed control effect with the herbicidal composition is better than those with only butafenacil or only the phenoxycarboxylic acid type herbicide. With the composition, pesticide dose is reduced, and the adverse impact of pesticides to the ecological environment is reduced. Also, a weed pesticide resistance problem is effectively solved.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic composition pesticide that butafenacil and phenoxy carboxylic acid herbicides be active ingredient of take, be mainly used in uncultivated area, orchard, vine crop field weed and prevent and kill off, also can be used for wheat paddock weeding in seedling stage.
Background technology
Chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because careless ammonium phosphine large area is used separately, caused a lot of weeds to develop immunity to drugs.Simultaneously, grass when weeds occur is complicated mutually, not only annual and perennial weed is mixed raw, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, the staggered generation of low age, advanced age weeds, so when weed killer herbicide kind is used separately, all can show defect and limitation in a certain respect.
Butafenacil (butafenacil), non-selective uracil weeding agent, be mainly used in orchard, uncultivated area, Cotton Fields, vine crop field and prevent and kill off important broad leaved weed, grassy weed and sedge weed, also can be used for weeding before the crop seedlings such as wheat.
Phenoxy carboxylic acid herbicides is to inhale conduction hormone herbicide in selectivity, can destroy the conducting tissue of dicotyledon, and making to grow is interfered, cauline leaf distortion, and basal part of stem expands chap or cracking.Kind mainly contains 2 first 4 chlorine or 2 first 4 chlorine sodium, the different monooctyl ester of 2 first 4 chlorine, 2, and 4-drips, 2, and 4-d butyl ester or 2,4-drip different monooctyl ester etc.
The 2 first different monooctyl esters of 4 chlorine or 2 first 4 chlorine or 2 first 4 chlorine sodium or 2,4-drips or 2,4-d butyl ester or 2,4-drip different monooctyl ester and be applicable to prevent and kill off broadleaf weed as clearvers, chickweed, field bindweed, kitchen garden, water peanut, acalypha copperleaf etc., Grass Seedling is to its sensitivity.
Being mixed of different pesticide species is the common methods of the agriculture disease pest and weed of control.By formulation of pesticide, screening, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the drug-fast generation of disease pest and weed, is the important means that agricultural synthesis is administered.The inventor is to butafenacil, be mixed conducts in-depth research phenoxy carboxylic acid herbicides (the 2 first different monooctyl esters of 4 chlorine or 2 first 4 chlorine or 2 first 4 chlorine sodium or 2,4-drips or 2,4-d butyl ester or 2,4-drip different monooctyl ester), finds butafenacil, phenoxy carboxylic acid herbicides (the 2 first different monooctyl esters of 4 chlorine or 2 first 4 chlorine or 2 first 4 chlorine sodium or 2,4-drips or 2,4-d butyl ester or 2,4-drip a kind of in different monooctyl ester) is mixed to piemarker (Abutilon theophrasti), reed (Phragmites australis), cogongrass (Imperata cylindrica), barnyard grass (Echinochloa crusgalli), eleusine indica (Eleusine indica), deceive grass (Beckmannia syzigachne), pivot holds (Polygonum aviculare), pale persicaria (Polygonum lapathifolium), Ambrosia trifida (Ambrosia trifida), lamb's-quarters (Chenopodium album), chenopodium glaucum linn (Chenopodium glaucum), black nightshade (Solanum nigrum), feather cockscomb (Celosia argentea), Amaranthus retroflexus (Amaranthus retroflexus), beggar-ticks (Bidens pilosa), field thistle (Cirsium setosum), chickweed (Stellaria media), Herba Cyperi Glomerati (Juncellus serotinus), the rhizome of nutgrass flatsedge (Cyperus rotundus), difformed galingale herb (Cyperus difformis), the weeds such as Fischer grass (Scirpus triqueter) have synergistic function, after further study, have completed the present invention.
Summary of the invention
Technical problem to be solved: the object of the invention is to solve the deficiency in the single use of weed killer herbicide, a kind of efficient, low-cost, Herbicidal combinations of being conducive to the weeds comprehensive regulation is provided.
Technical scheme of the present invention is: a kind of Herbicidal combinations, and active ingredient is butafenacil and phenoxy carboxylic acid herbicides; Described phenoxy carboxylic acid herbicides be the different monooctyl ester of 2 first 4 chlorine, 2 first 4 chlorine, 2 first 4 chlorine sodium or 2,4-drips, 2,4-d butyl ester, 2,4-drips a kind of in different monooctyl ester; Butafenacil and the phenoxy carboxylic acid herbicides weight ratio in composition is 5:1～1:30, and butafenacil and phenoxy carboxylic acid herbicides weight summation percentage by weight in composition are 0.1%～90%, and surplus is insecticides adjuvant.
Composition pesticide of the present invention is prepared into a kind of of suspending agent, oil-suspending agent, water dispersible granules, wetting powder by pesticide production technology.The production technology of various application forms all belongs to existing known technology, does not repeat them here.
Composition pesticide of the present invention, can be applicable to prevent and kill off orchard, uncultivated area, vine crop field, Cotton Fields, weeds of wheat.
Composition pesticide of the present invention, adopts the method for spraying to use conventionally, also can adopt as required other operation techniques of the upper application of agricultural.
The present invention has following beneficial effect:
1, composition pesticide provided by the invention, in certain ratio range, show obvious synergistic effect, the control efficiency of composition is significantly improved than single dose, reduced the using dosage of agricultural chemicals, reduced medication number of times, reduce drug cost, reduced the adverse effect of agricultural chemicals to ecotope.
2, composition pesticide provided by the invention, two kinds of active ingredient mechanism of action are different, can overcome the shortcoming that long-term single use easily produces resistance, extend the service life of medicament, the comprehensive regulation important in inhibiting to Weed Resistance.
3, composition pesticide provided by the invention, use cost is low, easy to use, time saving and energy saving, and it applies huge economic benefit and social benefit.
