Description
One, technical field
The method of the composite use of a kind of Alon of the present invention belongs to the agriculture plant protection technical field, is exclusively used in the field-crop weeding.
Two, technical background
Using chemical herbicide is the most effective means in the farmland weed comprehensive regulation, but long-term high dose ground continuously uses kind or the single chemical herbicide of the mode of action, causes problems such as herbicide residue, environmental pollution and resistance and the development of pesticide resistance weeds easily.Reasonably the composite or mixture of chemical herbicide have enlarge kill the grass spectrum, improve herbicidal effect, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay weed killer herbicide drug resistance and advantages such as drug-fast generation and development, chemical herbicide is composite or to use be the important channel that addresses the above problem.Constantly riseing of exploitation new product weed killer herbicide enormous expenditure, and by contrast, exploitation is efficient with research, low toxicity, low-residual mixture of herbicides or mixture has small investment, the lead time is short and pay attention to extremely both at home and abroad, goes into overdrive one after another to develop to produce mixture of herbicides agent or mixture.Acetamide-group herbicides mainly absorb through coleoptile and the young shoot of plant, and the α-Dian Fenmei of sprout inhibition weed seed and protease activities are obstructed protein synthesis, cause the growth of plant sprout and root to stop, growing point death.Acetamide-group herbicides have the herbicidal effect height, selectivity is strong, and most of annual gramineous weeds are had special efficacy, and price is cheaper, be easy to degraded in plant corpus and in the soil environment, volatility is little, unionization, to the mammal low toxicity, safe in utilization, succession crop there are not advantages such as influence; Defectives such as but relatively poor to broad leaved weed and perennial weed preventive effect, herbicidal spectrum is narrower, and most kinds are processing soil treatment agents, only can use before crop is broadcast the back seedling, can only kill the weeds of firm sprouting, and is invalid to the weeds that emerged, and working life and lasting period are short; From twentieth century since the sixties, acetamide-group herbicides are good because of its herbicidal effect, selectivity develops rapidly by force becomes the important weed killer herbicide of a big class, be widely used in all kinds of crops field management of weeds, domestic existing nearly more than 20 tame agricultural chemicals enterprise production acetamide-group herbicides, wherein Acetochlor, butachlor are domestic main weed killer herbicide kind.Isoproturon belongs to phenyl ureagroup herbicides, and annual gramineous weed and a part of broad leaved weed are all had good preventive effect, is absorbed as the master with root system, be inhibitor of photosynthesis, make plant hungry and dead, working life is longer, can be before the crop seedling, use behind the seedling, it is longer to have the lasting period simultaneously, can reach 2-3 month, a little less than the volatility, decomposition of little, mainly by soil microbial degradation, the back stubble is had no adverse effects advantage such as environmental pollution is little; But the price of isoproturon is higher, and it is wide inadequately to kill the grass spectrum, to defectives such as sedge weed and perennial weed preventive effect are relatively poor.Isoproturon can be used for crop field managements of weeds such as wheat, cotton, corn, beans, and especially strong the and serious harm summer crops malignant weed of drug resistances such as Dui Wang grass, hard grass, Japanese amur foxtail, amur foxtail has good preventive effect.Acetamide-group herbicides are different with the isoproturon mechanism of action, and application mode is similar.But because people think that in idea they all are primarily aimed at annual gramineous weed, so still rare considering carried out composite report with both.Acetamide-group herbicides such as Acetochlor, butachlor etc. all belong to the large-tonnage agricultural chemicals at home, and exploitation is significant to prolonging old pesticide species use value with the weed killer herbicide kind composite or that use with of such weed killer herbicide further; In addition, before China becomes a full member of World Trade Organization, strengthen the deep development and the research of profound old brand large-tonnage weed killer herbicide kind, for protecting the agricultural chemicals industry of China also to have crucial meaning in the future.
Three, technical scheme
Technical problem the objective of the invention is at the price of isoproturon class weed killer herbicide in the prior art higher, it is wide inadequately to kill the grass spectrum, to defective such as sedge weed and perennial weed preventive effect be relatively poor, the method of the composite use of a kind of Alon is provided, solve that single weed killer herbicide kills grass spectrum relative narrower, the weed killer herbicide cost is higher and acetamide-group herbicides use short problems such as (only the soil treatment or the initial stage of emerging are effective emerging before) of optimum period, be applicable to the harm that the crop owner of farmlands such as preventing and kill off wheat, rape, corn, soybean, paddy rice, cotton and vegetables will single broadleaf weed.
The method of the composite use of technical scheme a kind of Alon provided by the present invention is: with Acetochlor, butachlor, isopropyl methoxalamine, propisochlor, the third careless amine, alachlor, naphthalene propionyl grass amine or contain composite dose of its composition with isoproturon by its active ingredient (weight) 0.5-3.0: 1 composite after, be used for the piece weeding of crop field according to its active ingredient 20-160 gram/mu.
The method of the composite use of above-mentioned a kind of Alon, it is characterized in that: with Acetochlor, butachlor, isopropyl methoxalamine, propisochlor, the third careless amine, alachlor, naphthalene propionyl grass amine or contain composite dose of its composition with isoproturon by its active ingredient (weight) 0.5-3.0: 1 composite after, again with metsulfuron-methyl, green sulphur is grand, tribenuron-methyl, ethametsulfuron, bensulfuron, pyrazosulfuron, thifensulfuron methyl, nicosulfuron or contain composite dose of its composition in its active ingredient (weight) with 15-150: after 1 ratio is composite, be used for the piece weeding of crop field according to its active ingredient 15-140 gram/mu.
In the method for the composite use of a kind of Alon of the present invention, composite according to the method described above after, can make suspension emulsion, wetting powder or missible oil and use.
The main advantage of method of the composite use of beneficial effect a kind of Alon provided by the present invention is:
1. with strong complementarity, safe.Acetamide-group herbicides are the weed killer herbicide of the different mechanisms of action of two classes with isoproturon, and are with strong complementarity.The two carry out composite after, enlarged and killed the grass spectrum, can prevent and kill off grass family, sedge family and the broad leaved weed of harm chief crop, between the two synergistic effect obvious, reduced consumption separately, crop safety is improved (seeing Table 1).
2. the formulation that can prepare is various, except that can be made into wetting powder, missible oil etc., also can be made into suspended emulsion, and is water-soluble better, and the preventive effect of main farmland weed all is significantly improved, and consumption obviously reduces.
3. applicable crops is in extensive range, can be applicable to staple crops: wheat, rape, paddy rice, corn, soybean, paddy rice, vegetables etc.
4. consumption is few, and the lasting period is moderate, and environmental pollution obviously reduces, and is better with environment compatibility, meets requirement on environmental protection.
