Abstract
The present invention discloses a kind of preparation method of gardening weed killer herbicide, described weed killer herbicide comprises active ingredient and auxiliary material, and described active ingredient is made up of Oxyfluorfen and Bentazon, wherein, the mass ratio of Oxyfluorfen and Bentazon is 1:5 ~ 5:1, active ingredient and auxiliary material is mixed to get.Oxyfluorfen and Bentazon composite after, there is obvious synergistic function.
Description
Technical field
The present invention relates to a kind of preparation method of gardening weed killer herbicide.
Background technology
Weed growth is rapid, not only fights for nutrient and moisture with flower plants and nursery stock, but also is the vector of multiple damage by disease and insect, if control will spread not in time, affects flowers and trees growth.Chemical herbicide controls the most effective mode of malignant weed, but the weed killer herbicide of single-activity composition exists defect in various degree on control of weeds, as lasting use is easily developed immunity to drugs, for avoiding developing immunity to drugs, usually a kind of medicament and another kind of medicament mixture are used.Oxyfluorfen and the contact weed killer herbicide of the equal property of Bentazon, but these two kinds of medicaments is composite there are no report.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of preparation method of composite gardening weed killer herbicide.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of preparation method of gardening weed killer herbicide, described weed killer herbicide comprises active ingredient and auxiliary material, and described active ingredient is made up of Oxyfluorfen and Bentazon, wherein, the mass ratio of Oxyfluorfen and Bentazon is 1:5 ~ 5:1, active ingredient and auxiliary material is mixed to get.
Preferably, the mass ratio of described Oxyfluorfen and Bentazon is 1:1 ~ 5:1.
Embodiment
Below in conjunction with preferred embodiment, the present invention will be described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment 1
Formula: the Oxyfluorfen+Bentazon (both mass ratioes are 1:1) of 30wt%, the emulsifier op-10 of 2wt%, the neopelex of 1.5wt%, the defoamer of 0.5wt%, surplus is water.Namely each component mixing and stirring is obtained composite weed killer herbicide.Co-toxicity coefficient (the abundant method of Sun Yun)=307.
Weed killer herbicide is watered dilution, and with spray pattern dispenser, dispenser 40 days " Invest, Then Investigate "s, to the herbicidal effect of lady's-grass, repeat 4 times, area 100m
2, active ingredient application dosage 180g/ hectare, strain preventive effect 90%.
Contrast: 1,480g/L Bentazon aqua active ingredient application dosage 1000g/ hectare, strain preventive effect 23%.
2,240g/L oxyfluorfen EC active ingredient application dosage 180g/ hectare, strain preventive effect 87%.
Embodiment 2
Formula: the Oxyfluorfen+Bentazon (both mass ratioes are 2.5:1) of 35wt%, the emulsifier op-10 of 2wt%, the neopelex of 2wt%, the defoamer of 0.5wt%, surplus is water.Namely each component mixing and stirring is obtained composite weed killer herbicide.Co-toxicity coefficient=460.
Weed killer herbicide is watered dilution, and with spray pattern dispenser, dispenser 40 days " Invest, Then Investigate "s, to the herbicidal effect of lady's-grass, repeat 4 times, area 100m
2, active ingredient application dosage 170g/ hectare, strain preventive effect 93%.
Embodiment 3
Formula: the Oxyfluorfen+Bentazon (both mass ratioes are 5:1) of 35wt%, the emulsifier op-10 of 3wt%, the sodium lignin sulfonate of 2wt%, surplus is precipitated calcium carbonate, makes wetting powder.Co-toxicity coefficient=330.
Weed killer herbicide is watered dilution, and with spray pattern dispenser, dispenser 40 days " Invest, Then Investigate "s, to the herbicidal effect of lady's-grass, repeat 4 times, area 100m
2, active ingredient application dosage 180g/ hectare, strain preventive effect 87%.
As seen from the above, Oxyfluorfen and Bentazon composite after, there is obvious synergistic function.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
