Abstract
The invention discloses a kind of all your compound methods with pretilachlor microemulsion, the product belongs to herbicide field；The present invention is raw material with that 14-15%, pretilachlor 5-6%, ethanol 6%, styrene 18%, water 56%, and by blending finished product under given conditions, the advantage of the production method is：Using common apparatus, process is simple, reaction condition be gentle, pollution-free waste discharge；All you and pretilachlor compounding have synergistic effect, after inciting somebody to action all thats and two kinds of herbicides of pretilachlor and auxiliary material compounding, the effect is significant of management of weeds is higher than alone all you or pretilachlor, product after the compounding good dispersion in water, it is active high, strong to various weeds permeability, adhesive force is good, and effective preventing weeding weeds effect is greatly enhanced.
Description
Technical field
The invention belongs to herbicide field, more particularly to a kind of all your compound methods with pretilachlor microemulsion.
Background technology
All you are amide-type selective herbicide, and sterling is colourless liquid, and odorless can be partially soluble in water when more than 20 DEG C, to people and animals' low toxicity.All you are main is absorbed by young shoot, conduction upwards, suppress the growth of young shoot and root, the protein synthesis of the main sprout inhibition seed of mechanism of action, secondly suppress choline and penetrate into phosphatide, interference lecithin is formed, and because the ability that grassy weed young shoot absorbs all thats is stronger than broad leaved weed, thus the medicine prevents and kill off the effect of grassy weed far better than broad leaved weed.All your missible oil is brown color liquid, emulsifiability is good, can mutually be mixed with many herbicides, it is used in dry crop more, such as vegetables, orchard, nursery, the broad leaved weeds such as annual gramineous weed and three-coloured amaranth, purslane such as eleusine indica, lady's-grass, green bristlegrass, cotton grass and cyperus iria, chufa, 20-50 days lasting period in soil can effectively be prevented and kill off.Pretilachlor, also known as ten safeners, pretilachlor is selective herbicide before the bud of amide-type rice field, live field and rice seedling bed can be can be safely used for, to a leaf wholeheartedly within barnyard grass preventive effect up to more than 95%, it is safe due to it, user can reduce application rate, seed spending is saved, is that increasing production of rice has laid reliable basis while reducing to the maximum sandwich barnyard grass of the paddy rice underproduction；Pretilachlor to weeds gramineous in addition to having good preventive effect, various annual nutgrass flatsedges and broadleaf weed can also be prevented and kill off, such as Monochoria vaginalis, difformed galingale herb, needle spikesedge herb, Eclipta prostrata, mexicana, Procumbent Falsepimpernel, false loosestrife, firefly Lin, cyperus iria, also there is simultaneous controlling and inhibitory action to knotgrass, water purslane, four leaf duckweed etc., anti- Weed-control effect difficult to moleplant seed etc. is notable, 30-50 days lasting period, substantially nursery period overall process weeds can be controlled, and it is easy to use, it is sprayed on seedling bed with sprayer after can directly diluting, fine earth can also be mixed, is spread on seedling face.All you have synergistic effect with pretilachlor compounding, and after above-mentioned two kinds of herbicides and auxiliary material compounding, the effect is significant for preventing and kill off paddy field weed is higher than alone all you or pretilachlor, and anti-herbicidal effect is greatly enhanced.
The content of the invention
Present invention mainly solves problem be to provide a kind of compound method of all you and pretilachlor microemulsion, produce the raw material that the product uses is by weight ratio：All your 14-15%, pretilachlor 5-6%, ethanol 6%, styrene 18%, water 56%.
The technical solution adopted by the present invention is：
（1）First the styrene of formula ratio is added in the first agitator tank, stirring is started under normal temperature, pretilachlor, the ethanol of formula ratio, stirring reaction 0.2-0.3 hours are added while stirring；
（2）First the water of formula ratio is added in high-speed stirred tank, stirring is started under normal temperature, the rotating speed of agitator is 30-40 revs/min, and all thats of formula ratio are added while stirring；The rotating speed of agitator in fast agitator tank is heightened for 210-220 revs/min, the mixture of styrene, pretilachlor, ethanol is slowly added into high-speed stirred tank, finished product is obtained after stirring reaction 0.5-0.6 hours.
Further technical scheme of the invention is：
Described all your purity is that the purity of 80%, pretilachlor is 25%.
Step（1）, step（2）Described normal temperature is 0-38 DEG C.
The beneficial effects of the invention are as follows：There is provided a kind of all your compound methods with pretilachlor microemulsion, the advantage of the production method is：Process is simple, environmental pollution is small, the reaction time is short, reaction condition is gentle, all you and pretilachlor compounding have synergistic effect, the effect is significant of product management of weeds is higher than alone all you or pretilachlor, product after the compounding good dispersion in water, it is active high, strong to various weeds permeability, adhesive force is good, and effective preventing weeding weeds effect is greatly enhanced.
