Problems solved by technology

[0003] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is easy to produce resistance, the herbicidal spectrum is not wide enough, and it can only control monocotyledonous or dicotyledonous weeds, or can only control emerging weeds. Weeds or unemerged weeds cannot be controlled at the same time
But the cost is higher

Embodiment 1

[0022] Embodiment 1, dosage form configuration embodiment:

[0023] 35% saflufenacil·metolachlor aqueous emulsion:

[0024] Fenflufenazole 5%;

[0025] Sperm metolachlor 30%;

[0026] 150# solvent oil 10%;

[0027] EO-PO block polyether 3%;

[0028] Ethylene glycol 3%;

[0029] Defoamer 0.2%;

[0030] Make up to 100% with deionized water.

[0031] The preparation method is as follows: after dissolving the active ingredients saflufenacil and metolachlor in a solvent, adding an emulsifier, mixing and stirring to form a homogeneous liquid, which is used as an oil phase component; dissolving antifreeze ethylene glycol and defoaming agent , deionized water, mix and stir evenly, as the water phase part. Using a high-speed shearing machine, the oil phase was pumped into the water phase and fully sheared to obtain a 35% saflufenacil·metolachlor aqueous emulsion.

Embodiment 2

[0032] Embodiment two, indoor biological activity measurement embodiment:

[0033] The present invention uses the Gowing method to evaluate the combined effect of the proposed compositions.

[0034] ;

[0035] where:

[0036] X—the weed control effect when the dosage of herbicide component A is P;

[0037] Y—the weed control effect when the dosage of herbicide component B is Q;

[0038] E 0 — the theoretical control effect when the dosage of herbicide component A is P + the theoretical control effect when the dosage of herbicide component B is Q;

[0039] E—the measured control effect after herbicide component A and herbicide component B are mixed in the above-mentioned proportions.

[0040] when E-E 0 When >10%, it is a synergistic effect; when E-E 0 When 0 A value between ±10% is additive. In the present invention, the indoor combined effect of herbicide active components A and B on weeds is determined through indoor pot experiments, and the combined effect of the...

Embodiment 3

[0046] Embodiment three, field herbicidal activity measurement embodiment:

[0047] The present invention also conducts the drug efficacy test on weeds on the formulation examples containing herbicide active component A and active component B by the method of field plot test, so as to clarify the control effect of the composition on non-cultivated weeds.

[0048] According to the different components of different formulation examples, pre-emergence soil treatment, early post-emergence and post-emergence stem and leaf spray treatments were carried out respectively. The speed is 640 mL / min, the adjustable conical nozzle (325787), the nozzle height is 0.5 meters, the spray width is 0.85 meters, the walking speed is about 16.7 meters per minute, and the spray volume is 450 liters per hectare.

Abstract

The invention discloses a herbicide composition containing saflufenacil, the herbicide composition contains two active components A and B, A is saflufenacil, B is selected from one of s-metolachlor, butachlor and acetochlor, preferably, A and B adopt the mass percent of 1: (1.5-10), and the composition can be prepared into various dosage forms. The weeding composition is suitable for preventing and removing annual and perennial weeds in garden land and uncultivated land, the two effective components are compounded to achieve an obvious synergistic effect, the prevention and treatment effect is improved, and the pesticide consumption is reduced.

Description

[0001] This application is a divisional application of the patent application with the application number of 2018112253305 and the title of "Herbicidal composition containing saflufenacil and its application". technical field [0002] The invention relates to a compound technology of agricultural herbicidal compositions. Background technique [0003] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is prone to produce drug resistance, the herbicidal spectrum is not broad enough, it can only control monocotyledonous weeds or dicotyledonous weeds, or it can only control emerging seedlings. Weeds or weeds that have not emerged, cannot be controlled simultaneously. Through the compounding of two or more active components, the control effect can be improved, the amount of active ingredients used can be reduced, the cost of control can be saved, the generation of weed resistance can ...
