Description
Technical field
The invention belongs to weed killer herbicide field, particularly relate to the compound method of a kind of azoles humulone and methoxone microemulsion.
Background technology
Azoles humulone have another name called good fortune agriculture, soon go out spirit, triazolone grass ester, carfentrazone, molecular formula is C15H14Cl2F3N3O3,
Former medicine outward appearance is sticky yellow liquid, be slightly soluble in water, very easily be dissolved in toluene, azoles humulone is a kind of contact killing type selective herbicide, under the condition having light, in chlcrophyll biosynthesis process, by the accumulation suppressing proporphyrinogen oxidase to cause poisonous intermediate, thus destroy the cell membrane of weeds, blade is dried up rapidly, dead, namely azoles humulone is absorbed by plant leaf blade in 15 minutes after spray medicine, it is not drenched with rain affects, after 3-4 hours just there is poisoning symptom in weeds, 2-4 days dead, its action character is that herbicide speed is fast, fool proof to succession crop, it is the fine herbicide that wheatland is eliminated spring, be mainly used in preventing and kill off broad leaved weed and nutgrass flatsedge, especially to clearvers, piemarker, red heart lamb's-quarters, shepherd's purse, wartwort, corn gromwell, the blank pipe weeds such as to lead a cow have excellent preventive effect, the weeds etc. sulfonylurea herbicide being produced to resistance have good activity.Methoxone is colourless crystallization, belong to lower toxicity weed killer herbicide, be slightly soluble in water, be soluble in the organic solvent such as ethanol, ether, 2 first 4 chlorine belong to phenoxy carboxylic acid selective herbicide, there is stronger Uptake and translocation, be mainly used in cauline leaf process after seedling, medicament, through cuticula and cytoplasma membrane, is finally transmitted to each several part, produces Different Effects at different parts to nucleic acid and protein synthesis, the synthesis of metabolism of nucleic acid and protein is suppressed at plant tip, photosynthesis growing point stopped growing, young leaflet tablet not tensible, until can not normally carry out; Be transmitted to the medicament of plant bottom, the synthesis of the nucleic acid that plant stem is organized and protein increases, and promote abnormal cell division, the tip of a root expands, lose the ability absorbing nutrient, cause cane distortion, deformity, screen casing blocks, and phloem destroys, organic matter transport is obstructed, thus destroy the normal viability of plant, finally cause Plant death, can be used for preventing and kill off most of annual broadleaf weed.Product of the present invention with azoles humulone for major ingredient, made by a series of blending technique for auxiliary material with methoxone, toluene, ether, alkylol polyoxyethylene groups ether sodium sulfate, water, this production method has series of advantages such as use common apparatus, technique is simple, reaction condition is gentle, pollution-free waste discharge, good product quality etc., product is good dispersion in water, active high, strong to target body weeds permeability, adhesive force is good, kills power powerful.
Summary of the invention
The problem that the present invention mainly solves is to provide the compound method of a kind of azoles humulone and methoxone microemulsion, produce this product with azoles humulone for major ingredient, with methoxone, toluene, ether, alkylol polyoxyethylene groups ether sodium sulfate, water for auxiliary material, obtained finished product is carried out by blending under given conditions, the advantage of this production method is: use common apparatus, technique is simple, reaction condition is gentle, pollution-free waste discharge, good product quality.The raw material weight proportioning of producing the use of this product is: azoles humulone 10-12%, toluene 14-16%, methoxone 4-6%, ether 8-10%, alkylol polyoxyethylene groups ether sodium sulfate 3-5%, surplus are water.
