Abstract
The invention discloses a broad-spectrum herbicide. The broad-spectrum herbicide is prepared from the effective ingredients in percentage by weight: 20-30% of metamitron, 20-40% of prometryn, 5-8% of butyl glycol ether, 5-8% of surfactant and the balance of water. The broad-spectrum herbicide is prepared through combining two effective active ingredients in a special proportioning ratio and being matched with related auxiliaries. The broad-spectrum herbicide has the advantages that no precipitation exists during long-time storage, the dosage is low, the efficiency is high, and the drug effect duration is long. The broad-spectrum herbicide has the best prevention effect on just-germination weed, is broad in weed control spectrum and can be used for preventing and weeding gramineae weed and broad-leaf weed.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of broad spectrum type weed killer herbicide.
Background technology
Agricultural chemicals can be used for the biology of kill insects, fungi and the growth of other damages to crops.The agricultural chemicals using the earliest has dichlorodiphenyl trichloroethane, hexachlorcyclohexane etc., and they can eliminate destructive insects in a large number.But their good stability can exist for a long time in environment, and constantly accumulation in animals and plants and human body, be eliminated for this reason.Use afterwards organophosphorous pesticide instead, as dichlorvos etc., substituted initial agricultural chemicals.But their toxicity is too large, very large to people and animals' harm.In recent years, the agricultural chemicals appearance of a collection of high-efficiency low-toxicity, people have found and have had narrow spectrum agricultural chemicals, i.e. steroids agricultural chemicals now.
Rapidly, industry totally presents good developing state to China's pesticide market development, has developed into world's second largest pesticide producing state, 2012, Chemistry In China pesticide original medicine (folding active ingredient 100%) output reaches 354.9 ten thousand tons, increases by 34.0% on a year-on-year basis, for agricultural production provides important support.
International pesticide market is oligopoly general layout, and developed country's pesticide producing enterprise market share accounts for ninety percent.Approximately family more than 2000 of pesticide producing enterprise of current China, production capacity is comparatively disperseed, scope of the enterprise is generally less, research and development ability a little less than, there is no oneself core competitiveness.The most main products of producing Patent expiry of small business, profit is low, and burden is heavy, larger with countries in the world gap.By modes such as merging and reorganization, product restructuring and production capacity expansions, China-based enterprise's strength constantly strengthens, and has emerged a collection of leading enterprise with demonstration leading role.Meanwhile, the Chinese Enterprise autonomous sci-tech innovation ability of also more and more paying attention to and increase input, to high in technological content projects such as emerging biopesticide, low-toxin farm chemicals, plant growth regulator, has also obtained the achievement much attracting people's attention.
Agricultural chemicals is lost in environment, will cause serious environmental pollution, sometimes even causes extremely dangerous consequence.
1. atmosphere pollution, water environment, cause soil compaction.
The agricultural chemicals being lost in environment passes through evaporation, transpiration, wafts among atmosphere, and the agricultural chemicals waving is adsorbed by airborne dust again.And diffusion with the wind.Cause the pollution of atmospheric environment.Agricultural chemicals in atmosphere, again by rainfall, these agricultural chemicals flow in water again, thereby cause the pollution of water environment, and to people, animal, particularly aquatile (as fish, shrimp) works the mischief.Meanwhile, be lost to the agricultural chemicals in soil, also can cause soil compaction.
2. strengthen germ, the pesticide resistance of insect to agricultural chemicals
The long-time same agricultural chemicals that uses, finally can strengthen the pesticide resistance of germ, insect.Must continue to increase the dosage of agricultural chemicals to the control of germ of the same race, insect later. not so can not reach the object of degerm, insect.Form vicious circle.
3. kill and wound beneficial organism
Most agricultural chemicals are without selectively killing and wounding various biologies, comprising the biology useful to people, as frog, honeybee, birds and earthworm etc.The minimizing of these beneficial insects, beneficial bird or extinction, in fact reduced the natural enemy of insect, can cause the increase of number of pest. and affect agricultural production.
4. wildlife and livestock and poultry are poisoning
Wildlife and livestock and poultry have eaten the food that speckles with agricultural chemicals, can cause their acute or chronic poisonings.Most importantly agricultural chemicals affects biological fecundity, if a lot of birds and poultry are owing to being subject to the impact of agricultural chemicals, and the weight saving of laying eggs and eggshell thinning, easily broken.The extinction of many wildlifes and the pollution of agricultural chemicals have direct relation.
Therefore, how in the situation that ensureing drug concentration, reducing agricultural chemicals use is a problem demanding prompt solution on the impact of environment.
Summary of the invention
The object of the invention is to provide a kind of broad spectrum type weed killer herbicide, solves existingly need to use different agricultural chemicals to cause the problem of pesticide pollution environment in order to kill different insects.
Technical scheme of the present invention is: a kind of broad spectrum type weed killer herbicide, in active ingredient, the weight of this agricultural chemicals consists of: metamitron 20-30%, prometryn 20-40%, butyl glycol ether 5-8%, surfactant 5-8%, surplus is water.
Further, the weight of this agricultural chemicals consists of: metamitron 20-30%, prometryn 20-40%, butyl glycol ether 5-8%, surfactant 5-8%, surplus is water.
Preparation method is: after above-mentioned raw materials is mixed, carry out ultrasonic agitation, make it fully emulsified, to obtain final product.
Metamitron, other titles of Chinese: benzene piperazine grass, cyclizine, English common name: metamitron, molecular formula: C
