Abstract
A chemical herbicide contains paraquat solution (40-120 wt portions) glyphosate (40-120) and synergist (2-25). Its advantages are broad spectrum, high effect and safety, quickly taking its effect (2-3 days), low cost and less environmental pollution.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, particularly relate to a kind of chemical herbicide.
Background technology
No-tillage cultivation is the new model of arviculture in recent years, and its method is, crops need not farming before broadcasting and planting, and prevents and kill off to broadcast with steriland herbicide earlier and plants preceding weeds, treats that effect of herbicides is directly broadcast later to plant crops.Multiple kinds of crops productions such as paddy rice, wheat, rape, corn and vegetables have been widely used in.And the technology of no-tillage cultivation most critical is to broadcast to plant preceding chemical weed control.20% no track aqua of gram and 41% farming reach aqua two class steriland herbicides because of its broad weed-killing spectrum, and preventive effect is more thorough, and persticide residue is low, to advantages such as succession crop safety, is widely used in multiple kinds of crops no-tillage field chemical weed control.But because the long-term result that uses, the remaining weeds that two class weed killer herbicides can not be prevented and kill off, along with quantity increases, succession is the malignant weed that no-tillage field is difficult to prevent and kill off gradually, as Mazus japonicus, mud flowers and plants, Hairy Bittercress, caput grass etc., become a great problem of crops no-tillage cultivation.
Summary of the invention
The objective of the invention is to overcome the weak point of above-mentioned two class weed killer herbicides, provide a kind of and can prevent and kill off nearly all weeds, comprise the malignant weed that is difficult to prevent and kill off, and chemical herbicide quick-acting, safe in utilization.
Chemical herbicide of the present invention comprises that no track aqua 40～120,41% farming of 20% gram reaches aqua 40～120, synergist 2～25, and wherein, the no track aqua chemical name of 20% gram is 1,1 '-dimethyl-4,4 '-bipyridine cation salt; It is N-(phosphine carboxylic acid methyl) glycine that 41% farming reaches the aqua chemical name; Synergist is double to kill, save money at least a among spirit, 98% azone, the 95%HP-1 etc.
When weed killer herbicide of the present invention uses, the weed killer herbicide that has prepared is shaken up, broadcast in no-tillage crop field and plant dispenser in preceding 3～10 days.According to careless feelings decision consumption, general consumption is 100～200ml/ mu, and converting the water yield is 20～60 kilograms.
The advantage of chemical herbicide of the present invention is broad weed-killing spectrum, and is effective to all weeds, and the weeds root system can be killed, and comprises Mazus japonicus, mud flowers and plants, Brittle Falsepimpernel Herb, Hairy Bittercress, polygonum flaccidum, caput grass etc.And safety is good, to this season and following season plant growth safety.Quick-acting is good, meets rain in two hours after the dispenser, and most weeds are still had higher preventive effect, and behind the medicine 2～3 days, multiple weeds began death.Cost is low, is 6 yuan as mu cost of the present invention, restrains no track, farming reaches is 7 yuan, and the gram grass is 9 yuan soon, and environmental pollution is little.Being applicable to that no-tillage fields such as wheat, rape, paddy rice, corn and various vegetables are broadcast plants preceding weeding, also can be used for the big orchard weeding of fruit tree and weeds potential difference.
Embodiment 1:
Proportioning (by weight): the no track aqua of 20% gram (Switzerland Syngenta Co.,Ltd 100
41% farming reaches aqua (U.S. Monsanto Company) 50
95%HP-1 (Yibin City foreign trade Dongshan industrial corporation) 15
Preparation: above-mentioned three kinds of medicaments are poured in plastics or the glass container, stirred, sealing is preserved stand-by.
Test: experimental field (stockaded village village, yellow nail town, Shuangliu County, Chengdu, 1850 square metres of areas) is preceding stubble paddy rice, the soup for preparing broadcast in wheat, rape planted dispenser in preceding 4 days.Caput grass, Mazus japonicus and Hairy Bittercress are carried out efficiency test.And reach aqua with 20% gram no track aqua, 41% farming respectively and 20% gram grass weed killer herbicides such as fast (Switzerland earlier just company) compares test, do blank test simultaneously.The result is in shown in table 1-1, table 1-2, the table 1-3.As can be seen, the present invention has the advantage that gram no track, farming reach, restrains careless fast three kinds of weed killer herbicides from above-mentioned table, but its mu effective dose is lower than first three kind weed killer herbicide.As after the medication 15 days, 30 days, during consumption 165ml/ mu of the present invention, be 100% to three kinds of weeds preventive effects; When three kinds of weed killer herbicide consumptions were 200ml/ mu, restraining no track was 100% to caput grass and Hairy Bittercress preventive effect, but invalid to Mazus japonicus; Farming reaches caput grass and Mazus japonicus preventive effect 100%, but invalid to Hairy Bittercress; The gram grass is 100% to caput grass and Hairy Bittercress preventive effect soon, but Mazus japonicus fresh weight preventive effect is respectively 88.3%, 63.6%.
