Abstract
Disclosure one herbicidal methods, after composite to Oxyfluorfen and bentazone, imposes on weeds, and wherein, the mass ratio of Oxyfluorfen and bentazone is 1:5～5:1. After Oxyfluorfen is composite with bentazone, there is obvious synergistic function.
Description
Technical field
The present invention relates to a kind of herbicidal methods.
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 pest and disease damage, if preventing and treating will spread not in time, affect HUAMU and grows. Chemical herbicide is to control malignant weed most effective way, but, there is defect in various degree in the herbicide of single-activity composition, be easily generated Drug resistance as persistently used on control of weeds, for avoiding developing immunity to drugs, generally one medicament is used with another kind of medicament mixture. Oxyfluorfen and the equal contact herbicide of property of bentazone, but both medicaments is composite there are no report.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of herbicidal methods.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of herbicidal methods, after composite to Oxyfluorfen and bentazone, imposes on weeds, and wherein, the mass ratio of Oxyfluorfen and bentazone is 1:5～5:1.
Preferably, described Oxyfluorfen is 1:1～5:1 with the mass ratio of bentazone.
Detailed description of the invention
Below in conjunction with preferred embodiment, the present invention will be described, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Embodiment 1
Oxyfluorfen+the bentazone (both mass ratioes are 1:1) of formula: 30wt%, the emulsifier op-10 of 2wt%, the dodecylbenzene sodium sulfonate of 1.5wt%, the defoamer of 0.5wt%, surplus is water. Namely each component mixing and stirring is obtained composite herbicide. Co-toxicity coefficient (the abundant method of Sun Yun)=307.
Herbicide is watered dilution, with spray pattern dispenser, the 40 days " Invest, Then Investigate "s of the dispenser herbicidal effect to Herba Digitariae, repeats 4 times, area 100m2, effective ingredient application dosage 180g/ hectare, strain preventive effect 90%.
Comparison: 1,480g/L bentazone water preparation effective ingredient application dosage 1000g/ hectare, strain preventive effect 23%.
2,240g/L oxyfluorfen EC effective ingredient application dosage 180g/ hectare, strain preventive effect 87%.
Embodiment 2
Oxyfluorfen+the bentazone (both mass ratioes are 2.5:1) of formula: 35wt%, the emulsifier op-10 of 2wt%, the dodecylbenzene sodium sulfonate of 2wt%, the defoamer of 0.5wt%, surplus is water. Namely each component mixing and stirring is obtained composite herbicide. Co-toxicity coefficient=460.
Herbicide is watered dilution, with spray pattern dispenser, the 40 days " Invest, Then Investigate "s of the dispenser herbicidal effect to Herba Digitariae, repeats 4 times, area 100m2, effective ingredient application dosage 170g/ hectare, strain preventive effect 93%.
Embodiment 3
Oxyfluorfen+the bentazone (both mass ratioes are 5:1) of formula: 35wt%, the emulsifier op-10 of 3wt%, the sodium lignin sulfonate of 2wt%, surplus is precipitated calcium carbonate, makes wettable powder. Co-toxicity coefficient=330.
Herbicide is watered dilution, with spray pattern dispenser, the 40 days " Invest, Then Investigate "s of the dispenser herbicidal effect to Herba Digitariae, repeats 4 times, area 100m2, effective ingredient application dosage 180g/ hectare, strain preventive effect 87%.
The present invention can also directly by commercially available 480g/L bentazone water preparation and 240g/L oxyfluorfen EC first with after blending by proportional quantity and being mixed, then dilute, spray pesticide.
As seen from the above, after Oxyfluorfen is composite with bentazone, there is obvious synergistic function.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement. All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
Claims (1)
1. except a method for Herba Digitariae grass, after composite to Oxyfluorfen and bentazone, imposing on weeds, wherein, the mass ratio of Oxyfluorfen and bentazone is 1:1～5:1.
