Abstract
The invention relates to an isoproturon and bensulfuron methyl combined herbicide, which is wettable powder. The active ingredients of the herbicide are bensulfuron methyl and isoproturon, which are mixed in a weight ratio of 1:2.4, and the total content of the active ingredients is 68 percent; an aid accounts for 2 to 10 percent of the weight of the preparation, a stabilizer accounts for 2 to 10 percent of the weight of the preparation and powder accounts for the balance. The isoproturon and bensulfuron methyl combined herbicide has the combined effects of soil treatment and stem leaf treatment; and when used in soil treatment, the herbicide can prevent and kill gramineous weed, broadleaf weed and nutgrass flatsedge in wheat fields and is safe to wheat, avoids influencing afterreap crop, improves weed control effect, reduces residual activity, reduces phytotoxicity to crop, delays the generation of medicament resistance in weed and succession of community and reduces medicament dose and environment pollution. Meanwhile, the herbicide helps to save time, labor and money and reduce the burdens on peasants.
Description
Technical field
The present invention relates to a kind of composition pesticide of weeding, especially a kind of isoproturon and bensulfuron-methyl complex weedicide.
Background technology
Isoproturon is the inner sucting conduction type processing soil treatment agent cauline leaf inorganic agent of holding concurrently, after medicament is absorbed by plant root, teach and be accumulated in the blade, suppress photosynthesis, cause weeds death,, be used for barley, wheat, cotton, peanut, corn, paddy rice, legume crop Tanaka and prevent and kill off annual weed people and animals' low toxicity, but its drug effect phase is shorter, kills grass and composes narrower.
Bensulfuron-methyl is a selectivity inner sucting conduction type weed killer herbicide, medicament is diffusion rapidly in water, transfers to other position after weeds root and blade absorption, hinders the branched-chain amino acid biosynthesis, the susceptible weeds GF is obstructed, tender tissue turns to be yellow too early, suppresses leaf portion, root growth.Can effectively prevent and treat rice field life in 1 year and perennial broadleaf weed and nutgrass flatsedge, can and pass to other positions by weeds root, leaf absorption, rice safety, using method is flexible, but bensulfuron-methyl is effective with interior weeds to 2 leaf phases, surpasses 3 leaf weak effects, and to barnyard grass grass weak effect.
Summary of the invention
Use the problem that runs into separately in order to solve isoproturon and bensulfuron-methyl, the present invention proposes a kind of isoproturon and bensulfuron-methyl complex weedicide, this complex weedicide has soil treatment and cauline leaf treatment effect concurrently, be used for soil treatment, can prevent and kill off the wheat paddock grassy weed, can prevent and kill off broad leaved weed and nutgrass flatsedge again, and to wheat safety, succession crop there is not influence, improved herbicidal effect, reduced residual activity, reduction delays the drug-fast generation of weeds and the succession of community to the poisoning of crop, reduce dosage, reduce environmental pollution, save time simultaneously, laborsaving, save money, reduce farmer's burdens.
The present invention realizes in the following manner: a kind of isoproturon and bensulfuron-methyl complex weedicide, this weed killer herbicide is a wetting powder, the effective ingredient of this weed killer herbicide is bensulfuron-methyl and isoproturon, and the two mixed proportion (weight ratio) is 1: 2.4, and the total content of effective ingredient is 68%; Auxiliary agent can be with sodium lignin sulfonate or calcium lignosulfonate, carboxymethyl cellulose, NNO, draw back powder, dodecyl sodium sulfate etc., auxiliary dosage is the 2-10% of preparation, all the other are supplied with pulvis, and dust diluent is clay, potter's clay, diatomite, white carbon, bentonite, attapulgite, talcum powder etc.
Isoproturon and bensulfuron-methyl mix and can cause that bensulfuron-methyl slowly decomposes, add BaSO4 or BaSO4 and phosphatic mixture in the preparation as stabilizing agent, effect is fine, used phosphate has dipotassium hydrogen phosphate or sodium, ammonium salt, potassium dihydrogen phosphate, sodium or ammonium salt etc., and the two gross weight of barium sulfate that is added and phosphate is the 2-10% of preparation
For bensulfuron-methyl is uniformly dispersed, is processed into female powder earlier, and then is processed into wetting powder of the present invention with usual method and isoproturon.
The invention has the beneficial effects as follows: this a kind of isoproturon and bensulfuron-methyl complex weedicide, have soil treatment and cauline leaf treatment effect concurrently, be used for soil treatment, the wheat paddock grassy weed can be prevented and kill off, broad leaved weed and nutgrass flatsedge can be prevented and kill off again, and to wheat safety, succession crop is not had influence, improved herbicidal effect, reduced residual activity, reduction is to the poisoning of crop, delay the drug-fast generation of weeds and the succession of community, reduction dosage, reduce environmental pollution, save time simultaneously, laborsaving, economical, reduce farmer's burdens.
The invention will be further described below in conjunction with embodiment.
Embodiment one
All the other add bentonite isoproturon 48%, bensulfuron-methyl 20%, white carbon 5%, KH2PO4 6%, BaSO4 2%, mixed wetting powder.
Embodiment two
Isoproturon 48%, bensulfuron-methyl 20%, sodium lignin sulfonate 3%, NNO2%, white carbon 6%, BaSO4 8%, potassium dihydrogen phosphate 4%, all the other add diatomite and make wetting powder.
Embodiment three (herbicidal effect and units increased in production analysis)
