Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of bare place complex weedicide containing glyphosate.
Background technology
The registration product for being presently used for bare place weeds mainly has the single doses such as glyphosate, glufosinate-ammonium, diquat dibromide and its compounding
Preparation, cut both ways, although as glufosinate-ammonium, diquat dibromide etc product quick-acting are good, but the lasting period is shorter, after meeting rain
Weeds are easily recurred.Glyphosate and its various salt herbicides, can be eradicated, but quick-acting is bad.Moreover, these weedings
Agent is undesirable to the herbicidal effect of the perennial weeds such as bamboo, reed, cogongrass, fevervine.
The patent network such as rise by one hundred to inquire about, the Patent No. of Hailir Pharmaceutical Group Co., Ltd.'s application
CN201510731448.5 patents disclose a kind of Herbicidal combinations containing haloxyfop-r-methyl and glyphosate.Guangxi is big
The Patent No. CN201310082628.6 patents for learning application disclose a kind of side for preventing and kill off Sedum alfredii Hance field grassy weed
Method.These patents have synergistic effect to grassy weed effect, but bad to the broad leaved weed effect such as fevervine.
Guangxi Sanjing Chemical Technology Co., Ltd. and the Patent No. of Chemical Industry Inst., Guangxi Zhuang Autonomous Region's application
CN201310491567.9 patent discloses the herbicidal composition of Glufosinate-ammoniumpesticideng, glyphosate and azoles humulone, solves small fly
Fluffy the problem of waiting weeds difficulty to prevent and kill off, but, easily recurrence not satisfactory to the perennial grassy weed effect such as bamboo, cogongrass.
The content of the invention
The difficult annual grassy weeds prevented and kill off such as eleusine indica, Horseweed Herb, and can be prevented and kill off it is an object of the invention to provide a kind of
The perennial weeds such as bamboo, reed, cogongrass, fevervine are prevented and kill off, and the bare place complex weedicide to work well.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：
A kind of bare place complex weedicide containing glyphosate, the effective ingredient in the complex weedicide is glyphosate, height
Haloxyfop-P-methyl and azoles humulone are imitated, the weight ratio of the glyphosate, haloxyfop-r-methyl and azoles humulone is 10~80：3~
20:1~20.
Further scheme, the weight ratio of the glyphosate, haloxyfop-r-methyl and azoles humulone is 25~40：2.5~4:
0.5~2.
Further scheme, the quality of the effective ingredient account for the 5~85% of the complex weedicide gross mass.
Further scheme, the formulation of the complex weedicide is missible oil, microemulsion, suspending agent, dispersible oil-suspending agent, micro-
Capsule suspending agent, suspension emulsion, aqua, microemulsion, wettable powder or water dispersible granules.
With the synergy after Sun Yunpei co-toxicity coefficient method evaluation mixture, glyphosate, efficient haloxyfop-methyl are as a result shown
Spirit and azoles humulone press 25~40：2.5~4:0.5~2, the co-toxicity coefficient of ratio compounding is significantly greater than 120, reaches notable synergy
Effect, illustrates glyphosate, haloxyfop-r-methyl or azoles humulone by 25~40：2.5~4:0.5~2 ratio mixture is to annual
Weeds even also have significant synergies to perennial weeds.
The logical field control effectiveness test too much of complex weedicide of the present invention shows, in annual grassy weeds or perennial weeds
Growth period different times are prevented and treated, and not only quick-acting is good, and the lasting period is grown, and with the increase of dosage, preventive effect is remarkably reinforced,
Not only herbicidal effect is notable, and environmentally friendly, on second stubble crop without influence.
Compared with prior art, complex weedicide of the present invention can prevent and kill off annual grassy weeds, can also prevent and kill off perennial
Weeds, it is environmentally safe, and succession crop is had a good application prospect without influence.

Embodiment 7：Complex weedicide field control effectiveness test of the present invention
Complex weedicide of the present invention was shown by the field control effectiveness test of 2 years, in weeds vigorous period, utilized this
The 36% glyphosate haloxyfop-r-methyl azoles humulone (azoles of+4% haloxyfop-r-methyl of 30% glyphosate+2% of invention
Humulone) dispersible milliliter/mu of oil-suspending agent (OD) dosage 80,100,120,200, it is watered 40 kgs/acre and sprays, 10 after medicine,
All preventive effects are surveyed within 30 days, as a result such as following table：
Note：In upper table, blank control is weeds quality (gram), and other is Weed-control effect (%).
By upper table it can be seen that：Milliliter/mu of herbicide 80 reaches more than 80% for 10 days to the preventive effect of eleusine indica, 30 days
Reach more than 95%, with the increase of dosage, preventive effect is remarkably reinforced；To 80 milliliters of the preventive effect of broad leaved weed lamb's-quarters and Horseweed Herb/
Mu reaches more than 80% for 10 days, reaches more than 90% within 30 days, with the increase of dosage, preventive effect is remarkably reinforced.It is miscellaneous to bare place
The preventive effect of grass, 100 milliliters/mu can have good herbicidal effect to weeds, with one of which active ingredient ratio is used alone
Compared with expanding herbicide controlling spectrum, have good preventive effect to single broadleaf weed.Not only herbicidal effect is notable, and to environment
Close friend, on second stubble crop without influence, the pollution to environment is small, to people, animal, birds and beneficial organism safety, is advantageous to keep life
State balances.In addition, the herbicide of the present invention is processed using physical method, and simple production process, three wastes row in production process
Put, ecological environment is had no adverse effects.It is the preferable complex weedicide of current prevention effect.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
