Abstract
The invention discloses a weeding composition containing bentazone and rimsulfuron. The composition is prepared from bentazone, rimsulfuron and pesticide adjuvants, wherein the weight ratio of bentazone to rimsulfuron is 1:1-1:20, and the total weight of bentazone and rimsulfuron accounts for 20-80 percent of weight of the weeding composition. The weeding composition is suitable for preventing and killing annual weeds in a potato field. Compared with a single agent, the weeding composition has the advantages that the synergic and addition effects are remarkable, the use amount of pesticide is reduced, the application cost is reduced, the service life of pesticide is prolonged, and adverse influence of pesticide on the ecological environment can be reduced.
Description
Technical field
A kind of Herbicidal combinations that the present invention relates to, specifically a kind of Herbicidal combinations containing bentazone and rimsulfuron.
Background technology
Weed eradication Pinus antifebrin class weed killer herbicide, absorbs mainly through weeds young shoot and immature secondary root, and suppress the synthesis of body internal protein, make the enlargement of weeds shoot, deformity, color depth is green, finally causes death.Can be used for anti-divided by the grassy weed of seed germination, annual nutgrass flatsedge and some annual broadleaf weeds.
Before rimsulfuron belongs to heterocyclic selectivity bud, post-emergence herbicide, contacted with medicament by weeds young shoot or seedling, absorb and cause effect, dispenser after seedling, weeds are absorbed by acrial part, medicament is accumulated in the vigorous position of growth after entering plant corpus, Developing restraint, causes weeds to organize perish.Competence exertion herbicide effect under illumination condition, but do not affect photosynthetic Hill reaction.Weeds from rudiment to the 2-3 leaf phase all to this susceptibility sense, best with weeds budding period pesticide supplying effect, with weeds grow up effect decline.To annual gramineae, sedge family, broad leaved weed and some perennial weed Be very effective.
The mixture of different pesticide species is the effective ways improving control efficiency, expanding prevention spectrum and delay agriculture disease pest and weed.By agricultural chemicals toxicity test, filter out rational proportioning, can effectively improve actual control efficiency, reduce dosage, reducing costs, delay the drug-fast generation of disease pest and weed, is the important means of the agricultural pest comprehensive regulation.The present inventor screens bentazone and rimsulfuron combination formula and conducts in-depth research, and finds that bentazone and rimsulfuron combination have synergy or summation action to potato fields main weeds, after further study, completes the present invention.
Summary of the invention
The object of the invention is to solve the single and effect poor of herbicidal spectrum in prior art, provide a kind of efficient, herbicidal spectrum is wide, delay pesticide resistance produces, and is beneficial to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention is applied to by this Herbicidal combinations to prevent and kill off potato fields annual weed.
The technical scheme realizing the object of the invention is: for achieving the above object, the invention provides a kind of Herbicidal combinations, be made up of active ingredient bentazone and rimsulfuron and suitable insecticides adjuvant, the ratio of weight and number of bentazone and rimsulfuron is 1:1-1:20, preferred weight portion rate is 1:1-1:5, bentazone and the percentage by weight of rimsulfuron weight summation in Herbicidal combinations are 20%-80%, and all the other are allow in agricultural chemicals to use and acceptable insecticides adjuvant.
Described Herbicidal combinations according to well known to a person skilled in the art method, can be mixed with the application forms of the applicable agricultural uses such as wetting powder, suspending agent, water dispersible granules.
Described Herbicidal combinations is also containing the auxiliary agent of preparation needed for pesticidal preparations, comprise the mixing of one or more in solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, defoamer, antifreezing agent, disintegrant, binding agent, filler, filler, deionized water etc., be known substance, various auxiliary agents conventional in pesticidal preparations, can change to some extent according to different situations, be not particularly limited.
The production technology of the various application forms of Herbicidal combinations provided by the invention all belongs to existing known technology, does not repeat them here.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of the present composition and amount of application have slight variations with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Herbicidal combinations provided by the invention, usually adopts the method for spraying to use, also can adopt other operation techniques agriculturally applied as required.
Herbicidal combinations of the present invention is applicable to prevent and kill off potato fields annual weed.
Compared with prior art, beneficial effect of the present invention is: 1. significantly improve preventive effect; 2. expand herbicide spectrum; 3. delay the generation of weeds to active component resistance; 4. reduce Pesticide use amount, thus reduce cost and decrease the impact on environment.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Preparation method embodiment 1:60% bentazone rimsulfuron wetting powder.
Mix entering in blender after following material in proportion coarse crushing, more namely obtain 60% bentazone rimsulfuron wetting powder after 2 air-flow crushings.
Preparation method embodiment 2:40% bentazone rimsulfuron suspending agent.
Following material is pulverized in proportion in advance, then adds in sand mill and grind, the obtained 40% bentazone rimsulfuron suspending agent system of allotment after high shear mixing.
