Technical Field

The invention relates to the technical field of pesticides, and particularly relates to a flufenacet-containing wheat field herbicide composition.

Background

With the use of herbicide products in large areas of wheat fields for many years, many problems are raised in the control of weeds in wheat fields: (1) the weed resistance is outstanding, and in recent years, as the use amount of the herbicide is increased year by year, the herbicide resistance is rapidly developed, and even a part of areas have appeared to be 'super weeds' with resistance to various herbicides; (2) the harm of perennial weeds becomes a major problem; (3) the weed control spectrum of the herbicide variety needs to be expanded, and the lasting period of the soil control agent is prolonged; (4) the demand for the herbicide variety with broad spectrum, strong selectivity and convenient use is more urgent.

In recent years, it has become a common technical proposal to perform synergistic action on different herbicides and expand the weed control spectrum so as to obtain better characteristics than a single herbicide.

Flufenacet is a cell division and growth inhibitor, and the main target site is fatty acid metabolism. Tolerance is attributed to rapid detoxification by glutathione transferase. Can be used before or after seedling, and the agent can be transported and distributed in crop body, and has meristem activity. At present, the herbicide is mainly used in corn fields, soybean fields, tomato fields, potato fields and sunflower fields before seedlings, and also can be used in corn fields, wheat fields and paddy fields after seedlings, and the dosage of the herbicide is about 0.9 kg/ha.

A highly selective oxime-flutole herbicide. Has the effect of internal absorption and conduction, and is used for preventing and killing various gramineous weeds in barley and wheat fields. After the foliage application, the weeds are quickly absorbed and transferred to the whole plant body, and the weeds lose green and die. The spraying amount is generally 150-350 g of active ingredients/hm 2. The dosage of the weed control wild oat is 200-350 g/hm2, and the weed control wild oat is effective from an early growth stage to a leaf separation stage and a jointing stage.

Various problems in the aspect of weed control are solved only by compounding different active ingredients. The compounding of different effective components has synergistic effect, can expand the prevention and treatment spectrum, and can solve the resistance problem caused by the use of a single medicament.

Disclosure of Invention

The invention aims to provide a wheat field herbicide composition which can expand the weed prevention spectrum, solve the weed resistance, reduce the use amount and improve the weed control effect by the synergistic effect of effective components in order to overcome the defects in the prior art.

The invention solves the technical problem, adopts the technical scheme that a wheat field herbicide composition containing flufenacet is provided, and comprises the following components: the composition comprises an effective component and an auxiliary component, wherein the effective component comprises flufenacet and tralkoxydim.

Select bentonite and white carbon black as solid filler for use, can play the effect of filler on the one hand, and can play the effect of tackifier, the bentonite can adsorb the active ingredient, can make its slow release drug effect, reach the effect of lasting weeding, white carbon black and diatomaceous earth are porous material, also can store post active ingredient, because the bentonite, white carbon black has certain viscidity, can stick the silk, the silk forms network form distribution on bentonite and white carbon black surface, further pin the active ingredient, slow down its release rate, the extension drug effect, and the silk can be well with the white carbon black and the bentonite that have adsorbed the active ingredient "grab" on ruderal root and blade, be difficult for being washed away by rainwater etc., the silk is as an animal protein, can be decomposed by the microorganism in the soil, can not cause the pollution for the environment. Glass bead can prevent on the one hand and precipitate for the medicament is more even, and on the other hand is lived the back by silk network form parcel, and glass bead gets into in the pore of diatomaceous earth and can firmly be pinned, strengthens the slow release effect of diatomaceous earth.

The invention has the following beneficial effects:

(1) the control effect of the herbicide composition on weeds in wheat fields is better than that of two active ingredients when the two active ingredients are applied independently.

(2) Due to the synergistic effect of the two effective components, the application amount of the herbicide composition is less than that of the two effective components when the two effective components are applied independently, and the application cost is reduced.

(3) The herbicide composition can be applied to prevent weeds from generating drug resistance, and the two active ingredients can prevent the weeds from generating single drug resistance variation, but cannot simultaneously perform variation towards multiple drug resistance directions.

(4) The herbicide composition is safe to wheat, meets the safety requirement of pesticide preparations, and has no damage effect on afterculture crops.
