The invention relates to pesticide, which in detail is a mixed herbicide with Pdibutalin, Pendimethalin and Imazethapyr. It is characterized in that it takes effective component of Pdibutalin, Pendimethalin and Imazethapyr to prepare mixed herbicide, adds proper amount of carrying agent or adjuvant to produce powder agent, wettable powder, water suspending agent, suspoemulsion microcapsules, missible oil, particle, soluble granule, dispersing granule and etc. The advantages of said herbicide are that it solves problem of no herbicide for dry rice field and enlarges weed removing range, it can control forage grass, perennial broadleaf weed and cyperus weed in the dry rice field, the herbicide consumption is dramatically reduced, and it is safe for crops in the field and the second stubble crops.

The present invention is directed to micro-encapsulated formulations of soil-active pest control and agricultural chemicals such as herbicides, insecticides, nematicides and fungicides (pesticides) that combine a strong initial activity and a longer residual activity in the soil than provided by current micro-encapsulated formulations. These formulations are prepared by combining two separate suspensions of microcapsules, containing one or more pesticides, which were separately prepared under differing conditions and therefore have significantly different chemical properties and field release rates. The present invention, in particular, is useful for the herbicide clomazone, alone or in combination with other herbicides.

The invention discloses a microcapsul water suspension agent of herbicide clomazone and preparation method thereof.

In the method, a plurality of crystallizers with a grading function are connected in series for operations, crystalline particles are graded for many times, and the product has high purity; and the method is favorable for subsequent clients with high requirements.

The invention discloses an achromobacter xylosoxidans and the application thereof in the degradation of clomazone. The achromobacter xylosoxidans is achromobacter xylosoxidans CGMCC No. 2773. The bacterial strain can grow in the environment of high concentration clomazone, and can degrade the clomazone with high efficiency, so as to provide important foundation for the study of micro-biological degradation of residual weedicide clomazone, thus being applied to biological purification of the water body and soil which are polluted by the clomazone.

The invention provides a herbicide compounded from benthiazole clomazone and metolachlor, and relates to the technical field of production of herbicides. The herbicide is composed of effective components of benthiazole clomazone and metolachlor, and the dosage form of the herbicide is a suspension or a wettable powder. The herbicide composition comprises the following raw materials by weight: 1 to 15% parts of benthiazole clomazone, 1 to 50% of metolachlor, 2 to 25 parts of an additive, and 10 to 96% of a filler. The herbicide provided by the invention is a herbicide pesticide composition, shows highly-efficient and broad-spectrum weeding performance, is mainly applied in prevention and control of annual weeds in corn fields, and has no adverse influence on crops.

A weed herbicide is prepared by the following raw materials by weight parts: 9.5 % of fomesafen, 2.5 % of quizalofop p ethyl, 23 % of clomazone, 42 % of 1,1'-dimethyl 4,4'-dichloro bipyridine, and 40 % of glyphosin. The weed herbicide can control various annual weeds, is strong in killing effect on perennial weeds, while underground stems and roots of the perennial weeds can sprout new branches, and has no influence on lignified brown stems and trunks. The weed herbicide is suitable for controlling weeds in orchards, mulberry gardens, rubber plantations and forests, as well as weeds at non-cultivated lands, ridges and road sides, and can control weeds for corns, sugarcanes, soybeans, nursery gardens and other wide-row crops by directed sprays. The weed herbicide can be further used as an auxiliary medicament used after a defoliant for machine harvested crops. For an ideal defoliating effect is not achieved when a harvesting stage is approaching after the crops are applied with the defoliant, the weed herbicide can be used to rapidly kill green tissues of the crops, dehydrate and dry the green tissues, and do not influence short-period stacking and transporting of the harvested fruits after a mechanical harvesting.

The invention discloses a weeding composition containing pretilachlor and clomazone for lotus root field. The composition comprises two active ingredients and the balance of pesticide adjuvants and carriers, wherein the two active ingredients are pretilachlor and clomazone respectively; the ratio of pretilachlor to clomazone is (1-50): 1; the weight of the two active ingredients accounts for 10%-50% of the total weight of the composition. The composition is prepared into emulsified oil, emulsifiable powder or fine granules.

The invention belongs to the field of agricultural chemicals and in particular relates to a paddy field synergistic weeding composition. The paddy field synergistic weeding composition is characterized by comprising the following active ingredients in percentage by weight: 5-40 percent of oxadiazon or 0.5-20 percent of oxadiargyl, 5-30 percent of pretilachlor or butachlor and 2-30 percent of clomazone. According to the composition, the weeding effect can be improved, the herbicide controlling spectrum is widened, the composition is low in toxicity and small in residual, and the pesticide hazard on rice is reduced. Moreover, the dosage, the administration frequency and the use cost are obviously reduced, the effect of the composition is obviously higher than that of each single-dose agent, and the paddy field synergistic weeding composition is suitable for controlling and eliminating of annual and perennial weeds in paddy fields.

The invention discloses a compound herbicidal composition.

The invention relates to a combined weed control formulation containing quizalofop-p-ethyl, fomesafen and clomazone and a preparation method thereof. The preparation method comprises the following steps: adopting an emulsifiable solution formulation, in which the total weight of the quizalofop-p-ethyl, the fomesafen and the clomazone is 18 percent; and the fomesafen is mixed with organic amine in advance to form salts according to the proportion of 1:5-5:1 by percentage by weight, so that the salts can be dissolved in vegetable oil or derivatives of the vegetable oil; and mixing the salts with the quizalofop-p-ethyl and the clomazone, adding 1 to 3 weight percent of isobutyl alcohol and 5 to 10 weight percent of emulsifier into the mixture to give the emulsifiable solution with transparent and uniform state, and taking the balance as the vegetable oil or the derivatives of the vegetable oil of a solvent. Compared with the prior art, the combined weed control formulation has the advantages that the reaction of raw medicines of diphenyl ether substances such as the fomesafen, and the like and the organic amine is performed to generate amine salts in advance, so that the amine salts can be dissolved in an environment-friendly vegetable oil solvent to realize the abandon of the prior solvent which is harmful to the environment and represented by DMF.
