Description
Technical field
The present invention relates to technical field of pesticide, in particular to a kind of compound herbicide for paddy fields.
Background technology
Live field, is, after rice seed is soaked seed 2～3 days germinateing, directly shed toward rice field, is most saving of labor, but lodging resistance in rice ability is general, and diseases and insect pests resistance is poor, is only suitable for machine receipts；Seedling throwing field, is that rice seed is firstly placed on the seedling bed of seedling room to germinate, and manually sheds in rice field with rice-seedling throwing machine or utilization after 20～30 days again, seedling throwing field has saving rice seedling bed, improves the advantages such as yield is useful, but lodging resistance in rice ability is poor, hand harvest is inconvenient, is suitable for machine and receives；Transplant field, it is rice seed is firstly placed in the container of seedling room or seedling bed germinates, then is multicast in rice seedling bed, again by rice transplanting to rice field after about 30～40 days, the Oryza sativa L. of transplant field has the advantages such as lodging tolerance is strong, diseases and insect pests resistance is strong, and hand harvest is convenient.Statistical data shows: do not use herbicide, and the impact on live real estate amount is 60%～80%, and the impact on seedling throwing field yield is 40%～60%, and the impact on the transplant field yield turned over is 20%～30%.Therefore, paddy field must carry out management of weeds.Broad leaved weed is based on sulphonyl class herbicide, and grassy weed is based on the herbicide such as amide-type or hormones.In order to expand herbicidal spectrum or potentiation, the herbicide of several types is usually carried out composite by people.But the use all the year round due to these herbicides; so weeds create resistance (time limit that herbicide of the prior art is produced resistance by weeds was typically in 15 years) gradually; in use it is accomplished by strengthening the consumption of herbicide; and this kind of operation; also Oryza sativa L. can be produced poisoning killing weeds simultaneously; if and protection Oryza sativa L. and in herbicide, add safener, the consumption of herbicide can be greatly increased again.It addition, highly active for dry land herbicide is added safener be used for rice terrace, also harm can be brought to environment.
In fact, main weeds is broad leaved weed and the big class of grassy weed two, is live at present and rice transplanting first order issue.Existing live field weeding requires over weed control in three weeding guarantee paddy fields, does not affect the yield of Oryza sativa L., also needs to carry out " inside front cover kills three benefits " operation, wastes man power and material in large quantities.
Summary of the invention
It is an object of the invention to provide a kind of compound herbicide for paddy fields, this compound herbicide for paddy fields has good herbicidal effect, and the service life is long, and can effectively reduce the injury to environment.
This invention address that it technical problem is that to realize by the following technical solutions:
A kind of compound herbicide for paddy fields, is mainly made up of following raw material:
Pyraclonil 0.05～49.7%；
Herbicide 0.3～49%；
Adjuvant surplus；
Herbicide is one or more in KIH 6127, mesotrione, fluorine ketone sulphur grass amine, promazine Sulfometuron Methyl, dichloroquinoline oxadiazon, cyhalofop-butyl.
Relative to prior art, the present invention includes following beneficial effect: the present invention utilizes pyraclonil for major ingredient, it is aided with other herbicide, it is re-dubbed compound herbicide, this compound herbicide belongs to the herbicide of type of tagging, make weeds be absorbed by root, stem, leaf, hence in weeds body, weeds are purged.This compound herbicide is applicable to rice direct seeding field and seedling throwing field, and it can effectively kill the resistant weed that sulfonylurea, amide-type, hormones weeds and other mechanism of action are similar, protects immature rice seedlings, does not produce poisoning；Expand herbicide spectrum；Its herbicidal effect is good, it is only necessary to " inside front cover kills " operation can removing weeds more thoroughly, so, it is possible effectively to reduce dosage and weeding times for spraying, effectively reduce the injury to environment.It addition, empirical tests, the compound herbicide for paddy fields service life provided by the invention is long, and it is produced resistance by weeds needs through more than 30 years.
Various types of paddy fields can be carried out weeding by compound herbicide for paddy fields provided by the invention, and particularly to the resistant weed in paddy field, elimination effect is excellent, wide spectrum, efficiently.In prior art, the weeding of live field is all adopt weed sprays, it is necessary to the sprinkling of artificial area one by one.And if compound herbicide provided by the invention makes solid, then spread fertilizer over the fields；If making liquid, then utilize current to spill and execute or carry out getting rid of to execute, so, greatly saved human cost.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, the technical scheme in the embodiment of the present invention will be clearly and completely described below.Unreceipted actual conditions person in embodiment, conventionally the condition of condition or manufacturer's suggestion carries out.Agents useful for same or the unreceipted production firm person of instrument, be and can pass through the commercially available conventional products bought and obtain.
Below the compound herbicide for paddy fields of the embodiment of the present invention is specifically described.
Current most herbicides all cannot be used for live field and seedling throwing field.And herbicide of the prior art has been produced serious resistance, the use for many years of herbicide of the prior art by weeds, the grass of weeds has been made to there occurs change mutually, accordingly, it is desirable to provide a kind of new herbicide.This new herbicide needs the technical problem overcome to have:
(1) by root, stem, leaf absorption, get to, in plant, kill weeds, to ensure the problem how safety of Oryza sativa L. makes plant absorption.The herbicide of 90% is all non-contact herbicide in the market, and pyraclonil is contact herbicide, but its weeding is thorough, uses the time also short, and by the current spraying level of China, if alone Foliage Absorption is easy to poisoning.
(2) owing to cultivating the change of custom, good environment is provided to the change of substantial amounts of weeds and grass phase, single by pyraclonil weeding, one is that dosage must be big, two is to produce how resistance overcomes the quick generation of resistance, can use by longer-term again, extend the time limit problem producing resistance.
(3) how with other mixture of herbicides, be prone to the technical problem of the agricultural dosage form absorbed being processed into weeds.
(4) how the growth rhythm of rice direct seeding field and seedling throwing field weeds overcomes that rice seedlings is little does not produce poisoning and the problem that can kill weeds.
Based on above-mentioned consideration, researcher is through long-term research and constantly practice, it is provided that a kind of compound herbicide for paddy fields, is mainly made up of following raw material:
Pyraclonil 0.05～49.7%；
Herbicide 0.3～49%；
Adjuvant surplus；
Herbicide is one or more in KIH 6127, mesotrione, fluorine ketone sulphur grass amine, promazine Sulfometuron Methyl, dichloroquinoline oxadiazon, cyhalofop-butyl.
Adjuvant includes:
Main auxiliary agent 1～20%；
Secondary adjuncts Balance；
Secondary auxiliary agent is filler or solvent.The percentage ratio of main auxiliary agent is identical with the percentage ratio radix of pyraclonil, herbicide, even total amount is 100%, then pyraclonil be 0.05～49.7%, herbicide be 0.3～49%, main auxiliary agent be 1～20%, surplus is secondary auxiliary agent, and four summations should be 100%.
