Abstract
The invention discloses a kind of Herbicidal combinations with synergistic effect, active ingredient flufenacet is contained in said composition He clomazone.The weight of active ingredient flufenacet and clomazone ratio can be 20~1：1~40.The test of pesticide effectiveness shows, said composition have with strong complementarity, synergistic effect is obvious, herbicide controlling spectrum expands, amount of application is reduced, the optimum period for applying fertilizer extends, environmental pollution high to crop safety reduces, with the positive feature such as environment compatibility is strong.
Description
Technical field
The invention belongs to agriculture plant protection field, more particularly to a kind of Herbicidal combinations for having and improving performance.
Background technology
Flufenacet (flufenacet) is found by Bayer Cropscience Co., Ltd, nineteen ninety-five is in Britain's Brighton plant protection meeting
The herbicide kind of upper introduction.The active component belongs to aryloxyl acetamide type compound together as mefenacet, with chloro second
Acetamide-group herbicides have similar control of weeds spectrum, can prevent and kill off annual gramineous weed, nutgrass flatsedge and some granules extensively
Broad leaved weed.Its action character is mainly played a role by suppressing cell division, is mainly used in corn, wheat, barley, soybean etc.
Annual gramineous weed such as Itanlian rye in the crop fields, and the before seedling after seedling early stage weeding of some broad leaved weeds.
Clomazone ((Command), also known as clomazone, is organic heterocyclic class selectivity herbicide before seedling stage.Suitable for preventing and kill off
Soybean, peanut, the annual gramineous weed and broad leaved weed in seeding corn and other crops field.Products characteristics：Lasting period is grown, and once uses
Medicine, drug effect is up to crop whole breeding time；Administration time is flexible, before seedling soil closing after seedling cauline leaf.Control object：Barnyard grass, dog
Tail grass, lady's-grass, setaria glauca, eleusine indica, black nightshade, elscholtiza, water spine pin, purslane, piemarker, flowerofanhour root or herb, lamb's-quarters, small lamb's-quarters, hold back indigo plant
Annual gramineaes such as dish, willow leaf thorn smartweed, pale persicaria, dayflower, dilute Xian of hair, bur beggar-ticks, beggar-ticks, Siberian cocklebur, artemisiifolia and wealthy
Leaf weeds.There is stronger inhibitory action to perennial field thistle, setose thistle, sowthistle, meadow pine etc..
Actual agricultural chemicals experience have shown that, repeat and single-minded carry out controlling weeds in many feelings using a kind of reactive compound
The fast selective of weeds will be caused under condition, prevent and treat injurious weed usually using the mixture of different activities compound at present.
By the way that the reactive compound with the different mechanisms of action is combined, can delaying drug resistance produce, reduce amount of application, reduce preventing and treating
Cost.
The content of the invention
The purpose of the present invention is to be directed to herbicide resistance and pedo relict problem in actual applications, is filtered out containing two
The herbicide of the different weeding principles of kind is compounded, and to improve herbicide prevention effect, delaying drug resistance produces, and reduces amount of application,
Reduce cost accounting.
It is a further object of the present invention to provide a kind of application of above-mentioned composition in agriculture field controlling weeds.
The purpose of the present invention can be reached by following measures：
The invention provides a kind of Herbicidal combinations with synergistic effect, contain effective constituents A and B in said composition,
Effective constituents A is flufenacet, active ingredient B Wei clomazones.
Inventor is found by experiment that above-mentioned Herbicidal combinations synergy is obvious, it is often more important that amount of application is reduced, and reduction makes
Contain that component A is different from component B compound structure type, and mechanism of action is different with cost, both can expand weeding at compounding
Spectrum, and generation and the development speed of Weed Resistance can be delayed to a certain extent, and no interactions between component A and component B
Resistance.
