Abstract
The invention relates to the technical field of pesticide production, and discloses a weeding composition recipe. The composition comprises two active ingredients of triaziflam and isoproturon; then, auxiliary agents such as thickening agents, dispersing agents, anti-freezing agents and defoaming agents are added and are mixed with water; high-speed shearing, wet-process sanding grinding and homogenizing filtering are performed; the materials are made into a suspending agent; the composition is obtained, wherein the weight ratio of the active ingredients of the triaziflam to the isoproturon is 1:(30-60). The weight percentage of the two active ingredients in the composition is 25 percent to 61 percent. The two active ingredients of the triaziflam and the isoproturon are compounded, so that the defect of single ingredients is overcome; the obvious synergistic effect is achieved; the safety is high; the weeding composition belongs to an ideal weeding composition.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of Herbicidal combinations with improvement, particularly relate to a kind of Herbicidal combinations containing trifluoro grass piperazine and isoproturon two kinds of active components.
Background technology
Trifluoro grass piperazine (trifludimoxazin), is researched and developed by BASF, belongs to Triazinone weed killer herbicide.ISO agricultural chemicals common name technical committee have approved its new active component common name according to agricultural chemicals common name outline (CPCN), has and well kill except effect, can use as new herbicides various crop weeds for 2014.
Isoproturon (isoproturon), the p-cumenyl-1 of 3-, 1-dimethyl urea, for substituted urea class selectivity inner-adsorption conduction-type herbicide, medicament, mainly through the Root Absorption of plant, is upwards transmitted in leaf with moisture in conduit, suppresses the photosynthesis of green plants, effectively can produce killing effect to grassy weed and part broad leaved weed, be Common Herbicides in cornfield herbicidal.But isoproturon in use requires higher, need time accurate, dose accurate, the freezing tolerance of wheat seeding can be reduced in addition.
Select novel herbicidal composition trifluoro grass piperazine, increase isoproturon and realize composite, to make up the deficiency of single dose, make the efficient Herbicidal combinations being applicable to the farmland such as wheat, corn, significant.
Summary of the invention
Be to provide one in the technical problem to be solved in the present invention and prevent and kill off wheat paddock, corn field weed Herbicidal combinations, without antagonism between each composition, can prevent and kill off grassy weed and can prevent and kill off broad leaved weed again, cost is low, easy to use, to wheat, corn safety.
In order to solve the problems of the technologies described above, the invention provides a kind of Herbicidal combinations, particularly, provide a kind of Herbicidal combinations containing trifluoro grass piperazine and isoproturon.Said composition contains trifluoro grass piperazine and isoproturon two kinds of active components, then adds the auxiliary agents such as thickener, dispersant, antifreezing agent, defoamer and water mixing, and through high speed shear, wet method sand milling, uniform filtration is made suspending agent and namely obtained said composition.Wherein the weight ratio of active ingredient trifluoro grass piperazine and isoproturon is 1:30--60, and two kinds of active ingredients percentage by weight is in the composition 25%-61%.
In above-mentioned composition, the weight ratio of active component trifluoro grass piperazine and isoproturon is 1:30-60.
In above-mentioned composition, two kinds of active components account for the 25%--61% of total composition altogether.
Preferably, in above-mentioned insecticides adjuvant, thickener is one or more in carboxymethylethylcellulose, hydroxypropyl methylcellulose, carboxymethyl cellulose, and the percetage by weight of thickener in Herbicidal combinations is 0.8%--1.2%.
Preferably, in above-mentioned insecticides adjuvant, dispersant is one or more in naphthalenesulfonate formaldehyde condensation compound D425, sodium methylene bis-naphthalene sulfonate NNO, agriculture breast 0201B, and the percetage by weight of dispersant in Herbicidal combinations is 1.5%--2.5%.
Preferably, in above-mentioned insecticides adjuvant, antifreezing agent is ethylene glycol, and consumption is the 3%--5% of Herbicidal combinations weight.
Preferably, in above-mentioned insecticides adjuvant, defoamer consumption is the 0.3%--0.5% of Herbicidal combinations weight.
Beneficial effect of the present invention: Herbicidal combinations of the present invention is mainly used in soil treatment, select novel herbicidal composition trifluoro grass piperazine, increasing isoproturon realizes composite, make the efficient Herbicidal combinations being applicable to the farmland such as wheat, corn, compensate for the deficiency of unitary agent, can annual gramineous weed be prevented and treated, broad-leaved section weeds can be prevented and treated again, have remarkable synergistic effect, and safety being good, is a kind of desirable Herbicidal combinations.
