Embodiment 195

[0032] Embodiment 195% pure fenoxaprop-prop-clodinafop-propargyl-fluroxypyr wettable powder

[0033] Fenoxaprop-methyl 90%, Clodinafop-propargyl 1%, Fluroxypyr 4%, Sodium Lignosulfonate 2%, Sodium Dodecylbenzenesulfonate 1%, Kaolin added to 100%, ready to prepare A 95% pure fenoxaprop-prop-clodin-propargyl-fluroxypyr wettable powder was obtained. Among them, fluroxypyr exists in the form of isooctyl ester.

[0034] Mix Fenoxaprop-P-P, Clodinafop-propargyl, Fluroxypyr, Dispersant (Sodium Lignosulfonate), Wetting Agent (Sodium Dodecylbenzenesulfonate), Filler (Kaolin Clay) in the mixing tank Mix uniformly in the medium, and then mix uniformly after being pulverized by a jet mill, and then the wettable powder product of the present invention can be made.

Embodiment 285

[0035] Embodiment 285% pure fenoxaprop-prop-clodinafop-propargyl-fluroxypyr water-dispersible granules

[0036] Fenoxaprop-p-ethyl 80%, clodinafop-propargyl 4%, fluroxyfen 1%, fatty alcohol polyoxyethylene ether 5%, saponin powder 4%, ammonium sulfate 2%, diatomaceous earth added to 100 %, 85% refined oxaprop-prop-clodinafop-propargyl-fluroxypyr water-dispersible granules were obtained. Among them, fluroxypyr exists in the form of isooctyl ester.

[0037] Fenoxaprop-ethyl, clodinafop-propargyl, fluroxyfen, dispersant (fatty alcohol polyoxyethylene ether), wetting agent (saponica powder), disintegrant (ammonium sulfate), filler (silicon algae) and so on to obtain the required particle size through airflow crushing to obtain the granulation material. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying.

Abstract

The invention belongs to the technology field of pesticide and discloses a mixed herbicide containing fenoxaprop-p-ethyl, clodinafop-propargyl and fluroxypyr. The herbicide takes fenoxaprop-p-ethyl, clodinafop-propargyl and fluroxypyr as main effective ingredients, wherein the mass ratio of fenoxaprop-p-ethyl to clodinafop-propargyl to fluroxypyr is (80-98):(0.1-10):(0.1-10). The invention also discloses application of the mixed herbicide to weeding in a paddy field. The mixed herbicide has broad weeding spectrum through mixture of weed killers, so as to improve the weeding effect; the mixed herbicide has the advantages of having quick effect, long lasting period, thorough weeding effect, low residue, low toxicity, safety, environment protection and the like and having capability of delaying pesticide resistance of the herbicide, and has prominent prevention and control effects on grassy weeds, broad leaf weeds, sedge weeds in the paddy field such as Alternanthera philoxeroides, amur foxtail and difformed galingale herbs.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a mixed herbicide containing fenoxaprop-ethyl, clodinafop-propargyl and fluroxyfen and an application thereof. Background technique [0002] Fenoxaprop-ethyl (fenoxaprop-ethyl), is a heteroepoxyphenoxypropionic acid herbicide, also known as Weiba, Puma, chemical name: (R)-2-[4-(6-chloro -1,3-Benzoxazole-2-oxyl)phenoxy]propionic acid ethyl ester. Fenoxaprop-p-ethyl is a selective systemic conduction post-emergence herbicide, which mainly inhibits the synthesis of fatty acids by inhibiting the key enzyme of fatty acid synthesis, acetyl-CoA carboxylase. The drug is absorbed and transmitted to the meristem and the growth point of the root through the stem and leaf, and the effect is rapid. After 2-3 days of application, the growth stops, and the heart leaves turn green and purple in 5-6 days, making the meristem brown, and the leaves gradually die. It ...
