Abstract
The invention relates to a high-efficiency weedicide composition containing tembotrione. A preparation of the weedicide composition contains two effective components A and B, wherein the component A refers to tembotrione and the component B refers to at east one of rimsulfuron and isoxadifen; the remaining components of the weedicide composition refer to an agricultural agent additive and a preparation for preparing complement component. When the component B refers to a composition of rimsulfuron and isoxadifen, the ratio of tembotrione to rimsulfuron to isoxadifen in parts by weight is (30-5) to (30-5) to (0.1-30), and the total parts by weight of the effective components A and B account for 1%-60% total parts by weight of the whole preparation. The weedicide composition has a remarkable synergistic effect, the effect duration performance of single dosage of each component is enhanced, the weedicide resistance of weeds is delayed obviously, the number of times of repeatedly using a weedicide is reduced, the use amount of the weedicide is lowered, and the agricultural cost is reduced; the weedicide composition is safe to crops and degrades easily in environment after the effect duration period; the safety of the weedicide composition to next season crops is enhanced, so that the weedicide composition has significance to ecological environment protection.
Description
Technical field
The present invention relates to agriculture chemical compounding technical field, be specifically related to a kind of efficient Herbicidal combinations that contains ring sulphur ketone.
Background technology
Ring sulphur ketone is a kind of novel three ketones weed killer herbicide, is similarly HPPD inhibitor, is mainly used in cornfield weeding.Its chemical structural formula is:
。
Isoxadifen (isoxadifen-ethyl), chemical name is 4,5-dihydro-5,5-diphenyl-1,2-azoles-3-carboxylic acid, ethyl ester, belongs to isoxazole class safener, is mainly used in preventing and kill off between corn field 1 year and raw weeds etc. throughout the year.Its chemical structural formula is:
。
Rimsulfuron belongs to sulfonylurea herbicide, branched-chain amino acid synthetic inhibitor, selective post-emergence herbicide.Be used for preventing and kill off corn field annual or perennial grass family and broad leaved weed, as creeping thistle, iron shepherd's purse, the rhizome of nutgrass flatsedge, curly dock, johnson grass, wild oat, Digitaria ischaemum (Schreib.) Schreib. Ex Mubl, barnyard grass, Annual Ryegrass, piemarker, Amaranthus retroflexus, clearvers, corn poppy, chickweed.Its chemical structural formula is:
。
Because the weed killer herbicide of applying in agricultural production is at present of a great variety, drug toxicity is large, and residual quantity is high, is easier to make weeds to produce resistance, and when the weed killer herbicide of single active ingredient uses, being subject to the factors such as resistance to affect its weeding effect can reduce greatly.If constantly formulate the former drug compound of novel weed killer herbicide, the initiative cycle of noval chemical compound is longer, drops into hugely, and current domestic agricultural chemicals enterprise is limit by scale, scientific research strength, and it is unpractical that former drug compound is carried out to creative research.And composite between agricultural chemicals can solve, agricultural chemicals single dose toxicity is large, the problem of weak effect, less investment again, R&D cycle are short, meet the present situation of domestic agricultural chemicals enterprise, and the mutual use between different agricultural chemicals can the drug-fast generation of retarding action thing, have comparatively desirable result of use, therefore between the different mechanism of action, the composite of agricultural chemicals is the study hotspot of current pesticide field.And ring sulphur ketone is a kind of novel three ketones weed killer herbicide, the mode of action is comparatively unique, and there is no cross resistance with other weed killer herbicides on domestic market, in order to delay weeds, the resistance of ring sulphur ketone is produced, and extends its market cycle.My research staff of company attempts encircling sulphur ketone and isoxadifen, rimsulfuron is composite; whether there is synergistic effect to observe it, through the checking of a large amount of indoor biometricses and field experiment, find to carry out taking ring sulphur ketone and isoxadifen, rimsulfuron as active ingredient composite after; weed eradication rate improves greatly; quick-acting is obviously strengthened, and also there is certain prolongation the lasting period, and dosage is lower; reduce agricultural cost; toxicity is less, and residual quantity still less, is conducive to environmental protection more.Can experiment confirms that both have very strong synergistic effect, and be that active principle carries out composite research with isoxadifen, rimsulfuron about encircling sulphur ketone, there is not yet at present relevant report at home and abroad.
