Abstract
The invention discloses an oxadiargyl and pyrazosulfuron compound oil suspending agent which comprises the following components in percent by weight: 1-40 percent of oxadiargyl, 1-20 percent of pyrazosulfuron, 10-60 percent of vegetable oil, 1-15 percent of a dispersing agent, 1-10 percent of a thickening agent and 10-30 percent of an emulsifying agent. A preparation method of the oxadiargyl and pyrazosulfuron compound oil suspending agent comprises the following steps of: 1, preprocessing the oxadiargyl, the pyrazosulfuron and the thickening agent; 2, mixing the dispersing agent, the emulsifying agent, the vegetable oil and materials preprocessed in step 1 and uniformly stirring; 3, putting the raw material uniformly mixed in step 2 into a sand mill, and sanding until the particle size is below 5 microns; and 4, filtering the sanded product. The oxadiargyl and pyrazosulfuron compound oil suspending agent has the characteristics of reducing dust pollution and consumption of pesticide, and improving the use effect.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Bing Que Evil humulone and the composite oil-suspending agent of pyrazosulfuron and preparation method thereof.
Background technology
Oxadiargyl (also claiming rice to think to reach) is a kind of diazole ketone bud phase selective herbicide of Rhone-Poulenc Company exploitation, the high-efficiency broad spectrum herbicides for use in paddy, remarkable to annual gramineae, sedge family, broad leaved weed and some perennial weed effect, malignant weed four leaf duckweeds there is good preventive effect.Be mainly used in preventing and kill off broad leaved weed before the seedlings such as paddy rice, potato, sunflower, vegetables, beet, orchard, as piemarker, beggar-ticks, Chenopodium weeds, Siberian cocklebur, dawrf mallow, Monochoria vaginalis, Polygonum weeds, plum blossom algae, black nightshade, common sow thistle, mexicana etc., grassy weed adds barnyard grass, moleplant seed, tribulus terrestris grass, Lan Macao, lady's-grass, eleusine indica, millet and belongs to weeds and sedge weed etc.
Pyrazosulfuron belongs to sulfonylurea herbicide, for the selectivity inner-adsorption conduction-type herbicide, mainly is absorbed by root system, shifts rapidly in weeds plant body, suppresses growth, and weeds are dead gradually.Paddy rice can be decomposed this medicament, on almost not impact of paddy growth.Efficacy stability, safe, lasting periods 25 ∽ 35 days.Can prevent and kill off annual and perennial broadleaf weed and sedge weed, as different in nature nutgrass flatsedge, Herba Cyperi Glomerati, firefly Lin, Monochoria vaginalis, Chinese celery, mexicana, angustifolia arrowhead herb, pondweed, blue or green duckweed, Eclipta prostrata, barnyard grass also be had certain preventive effect.
The third alkynes Evil humulone and the composite oil-suspending agent of pyrazosulfuron can be that weeds root system and cauline leaf absorb, can be after crop is broadcast before seedling or use vegetative period.Pyrazosulfuron can be absorbed by the root of weeds, stem, leaf, can effectively prevent and treat broad leaved weed and some nutgrass flatsedges; Bing Que Evil humulone is before the selectivity bud, post-emergence herbicide, can be absorbed by the young shoot of weeds or seedling, and weeds are responsive to Lonster to the 2-3 leaf phase from rudiment, can effectively prevent and treat annual gramineous weed and nutgrass flatsedge, part broad leaved weed.Pyrazosulfuron is different with Bing Que Evil humulone mechanism of action, herbicidal spectrum has complementary preferably, both mixedly can enlarge the herbicide spectrum, improve activity of weeding, reduce dosage, alleviate the poisoning that may occur, delay drug-fast generation, a dispenser solves the harm of weeds in whole breeding time substantially.
The common formulation of pyrazosulfuron has 10% wetting powder, the common formulation of oxadiargyl has 80% wetting powder, but this kind product produces a large amount of dust in process pollutes large to surrounding enviroment, multioperation personnel's health is also unfavorable, so the present invention adopts the wet grinding process exploitation to go out oil-suspending agent, to reduce the pollution of environment and operating personnel's damage.So the exploitation of Bing Que Evil humulone and the composite oil-suspending agent of pyrazosulfuron will produce great economic benefit and social benefit.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of Bing Que Evil humulone and the composite oil-suspending agent of pyrazosulfuron and preparation method thereof, have the consumption that reduces dust pollution, reduces agricultural chemicals, the characteristics that improve result of use.
To achieve these goals, the technical solution used in the present invention is: a kind of Bing Que Evil humulone and the composite oil-suspending agent of pyrazosulfuron comprise following component (by weight percentage):
Bing Que Evil humulone 1～40%, pyrazosulfuron 1～20%, vegetable oil 10%～60%, dispersant 1～15%, thickener 1～10%, emulsifier 10～30%;
Described vegetable oil is wherein any one or more than one mixture of soybean oil, oxidation soybean oil, peanut oil, corn oil, cottonseed oil, esterification soybean oil, esterification linseed oil, esterification sunflower oil, esterification cottonseed oil, esterification corn oil, esterification peanut oil.
Described dispersant is one or more the mixing of metal carboxylate dispersant, lignin sulfonate dispersant, naphthalenesulfonate dispersant.
Described thickener is one or more mixing of organobentonite white carbon, aluminium-magnesium silicate.
Described emulsifier is one or more mixing of styryl APEO and alcohol-ether mixture, alkylphenol polyoxyethylene formaldehyde condensation products, phosphorous acid esters, alkyl benzene calcium sulfonate.
A kind of Bing Que Evil humulone and the composite oil-suspending agent of pyrazosulfuron and preparation method thereof comprise the following steps:
1) Bing Que Evil humulone, pyrazosulfuron, thickener are carried out pretreatment after;
2) with dispersant, emulsifier, vegetable oil and step 1) the pretreatment material mixes and stirs;
3) with step 2) raw material that mixes drops in sand mill, sand milling to particle diameter less than or equal to 5um;
4) product that sand milling is good filters and gets final product at last.
Beneficial effect of the present invention:
1) to select the third alkynes Evil humulone and pyrazosulfuron to carry out composite in the present invention, finds that pyrazosulfuron when self has herbicide effect, has significant synergies to mancozeb, and the generation of the antagonism property of medicine has retarding action.
2) Herbicidal combinations herbicidal effect of the present invention obviously strengthens, and the weeds of different times are played the double effect of controlling of a medicine, drops into thereby reduce the manpower and materials of preventing and treating in the disease process, improves productivity effect.
3) the present invention adopts conventional method to prepare, and the preparation method is simple, and promotional value is very high.
