Problems solved by technology

[0004] At present, the herbicides used for weeding in non-cultivated land are limited by the herbicidal activity and herbicidal spectrum of a single herbicide. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds. The range of herbicidal spectrum is narrow, which can easily lead to weeds. drug resistance, or need to use higher doses

Embodiment 1

[0036] Herbicide composition formula according to L-glufosinate-ammonium 80%, propargyl fluorfen 0.5%, sodium dodecylbenzene sulfonate 3%, sodium alkylnaphthalene sulfonate 6%, GP polyoxyethylene block polymer 0.5% defoamer, diatomaceous earth as a carrier to make up to 100%; according to the conventional wettable powder preparation method, the fineness of the material pulverized by the jet mill reaches 98%, passes through a 325-mesh standard sieve, mixes evenly, and is formulated as a mass percent A wettable powder with a content of 80.5% (active ingredient).

Embodiment 2

[0038]The herbicide composition formula is supplemented by L-glufosinate-ammonium 50%, propargyl flufenamide 0.5%, sodium lauryl sulfate 3%, alkylaryl polyoxyethylene ether 5%, silicone oil 0.5%, and bentonite as a carrier. to 100%; according to the conventional wettable powder preparation method, the fineness of the material pulverized by the airflow mill reaches 98%, passes through a 325 mesh standard sieve, mixes uniformly, and is prepared into a wettable powder with a mass percentage of 50.5% (active ingredient) .

Embodiment 3

[0040] Herbicide composition formula according to L-glufosinate-ammonium 50%, propargyl fluorine 1%, sodium dodecylbenzene sulfonate 3%, alkyl naphthalene sulfonate 7%, ammonium sulfate 1%, methyl cellulose Su 1%, GP polyoxyethylene block polymer defoamer 0.5%, diatomaceous earth make up to 100%; According to the preparation method of conventional dispersible granules, pulverize through jet mill, then add binder, defoamer The foaming agent and water are mixed and kneaded to make a plastic material, which is put into a granulator to granulate, and the granulated product is dried to make a product with a mass percentage of 51% (active ingredient). Water-dispersible granules (WDG).

Abstract

The invention discloses a weeding composition containing L-glufosinate and flumioxazin and application of the weeding composition, which belong to the technical field of pesticides. The invention provides a herbicide which is high in efficiency, broad in weeding spectrum and long in duration and is capable of delaying resistance of weeds and takes the L-glufosinate and the flumioxazin as main effective ingredients. In the weeding composition, the L-glufosinate with higher activity is adopted, the weeding effect of the L-glufosinate, the weeding effect of the flumioxazin and the weeding effectof a mixture of the L-glufosinate and the flumioxazin are analyzed by studying weeding mechanisms of the L-glufosinate and the flumioxazin, and the control effect of the single dosage and the synergism of the mixture are comprehensively considered, so that the advantages and disadvantages of two effective ingredients for weeding: the L-glufosinate and the flumioxazin are complemented, the weed killing activity of the herbicide is greatly improved, the weeding spectrum is broadened, the dosage of the herbicide is remarkably reduced, the resistance of the weeds to the herbicide is reduced, the generation speed of the resistance of the weeds is decreased, the control effect of the herbicide resistant weeds is improved, therefore, the service life of the herbicide is prolonged, and the environment stress is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a herbicidal composition containing L-glufosinate-ammonium and fluflumecil and its application. Background technique [0002] Glufosinate and its salts, usually amine salts (Glufosinate ammonium), are organic phosphorus non-conductive herbicides and glutamine synthetase inhibitors, which can be used in citrus orchards, vineyards, tea gardens and other cultivated land It can effectively control more than 100 kinds of grass and broad-leaved weeds on land and non-cultivated land. Glufosinate-ammonium and its salts have the advantages of low toxicity, safety to crops, easy degradation in soil, low environmental pressure, broad herbicidal spectrum, and high herbicidal activity. The commonly used glufosinate-ammonium is a racemate. Compared with L-glufosinate-ammonium, its activity is on the low side, leading to an increase in t...
