Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of herbicide composition for paddy fields and application thereof.
Background technology
Chemical weed control is the anti-a good appetite suddenly appearing in a serious disease of farmland weed means the most economic, effective, but the long-term ground of high dose continuously uses the chemical herbicide of single variety or single model of action, it is easy to cause the problems such as weeds drug resistance and resistance evolution.The rationally composite or mixture of herbicidal compounds has expansion weeds spectrum, improves preventive effect, delays the advantages such as weeds drug resistance and drug-fast generation and development, is one of maximally efficient method solving the problems referred to above.
P _ Hydroxyphenyl pyruvic acid dual oxide enzyme (HPPD) is the another class new herbicides found after acetyl-CoA carboxylase (ACCase) inhibitor, acetolactate synthestase (ALS) inhibitor and proporphyrinogen oxidase (Protox) inhibitor etc..The action character of HPPD inhibitor is the activity of weeding with wide spectrum, and before bud and all can use after bud, weeds are dead after there is albefaction.Though the effect symptom fairly similar of its symptom and carotenoid biostatic agent, but its chemical constitution feature such as polarity and ionization degree have significantly different from known carotenoid biostatic agent.
HPPD inhibitor class herbicide Weed Resistance risk is significantly less than ACCase inhibitor, and is absent from, with other mechanism of action such as conventional ACCase inhibitor, ALS inhibitor, the cross resistance that target resistance causes.
Herbicide-safener (Safener), also referred to as antidote (Antidote) or protective agent (Protectant), is the chemical substance with special performance.Herbicide-safener is that cover crop exempts from herbicide damage selectively under not affecting the herbicide premise to target weeds activity, thus strengthening the crop tolerance to herbicide, increases the herbicide safety to crop.The states such as the U.S., Germany, Switzerland, Japan, Canada, Russia, Korea S and Hungary are more to the research of herbicide-safener, and China starts late, and just start this research at the end of the eighties.
Herbicide-safener can be divided into by compounds category: oxime ethers, dichloroacetyl amine, carboxylic acid derivates class, sulfonic acid class, azoles, thiazole and other heterocyclic compound, ketone and derivant thereof etc.；Can be divided into by structure: naphthalene acid anhydride class, dichloroacetyl amine, oxime ethers, heterocyclic, sulfonylureas (amine) class, plant growth regulator class, classes of herbicides and antibacterial class etc.；Can be divided into by model of action and action principle: conjunction type, breakdown type, antagonism type, offset-type etc..
Along with the extensive use of herbicide, herbicide damage problem constantly occurs that herbicide-safener is existed urgent needs.Herbicide-safener includes amide-type, carbamates, phenoxy carboxylic acid, aryloxyphenoxypropanoates class, sulfonylurea, sulfonamides, imidazolone type, cyclohexanedione class, isoxazole diones, sym-trinitrobenzene etc..The crop of protection mainly has Oryza sativa L., Sorghum vulgare Pers., Semen Maydis, Semen Tritici aestivi, rye (Secale cereale L.), Cotton Gossypii, Semen sojae atricolor etc..
The herbicide of current rice terrace application mainly has the minority kinds such as dichloro quinolinic acid, bispyribac-sodium, penoxsuam, cyhalofop-butyl.This several herbicides uses for many years on Oryza sativa L., weeds to penoxsuam, bispyribac-sodium, cyhalofop-butyl resistance problem start to highlight, especially at Direct-seeding Rice district current main flow herbicide, all barnyard grass is produced obvious resistance, and the herbicide-cyhalofop-butyl being uniquely used for Oryza sativa L. registration is also produced notable resistance by Semen Euphorbiae.Therefore need safety height, broad weed-killing spectrum badly on producing, can solve the problem that the kind of resistant weed problem.

C, field demonstration
Utilize embodiment 1)-22) prepare herbicidal composition prevent and kill off paddy field weed test.
Within 2014, carry out exemplary popularization test in Hubei public security, Poyang, Jiangxi, Wangcheng, Hunan, Shenyang, Liaoning, testing site, 25,5 rice belts of Sanya, Hainan.Different demonstration areas rice varieties refers to table 17.
Table 17 different demonstration areas rice varieties situation
| Demonstration area | Rice varieties |
| Hubei public security | The province of the Yuan Dynasty is live |
| Poyang, Jiangxi | Two excellent 287 |
| Wangcheng, Hunan | Huang Huazhan |
| Yingkou, Liaoning | Logical round-grained rice 89 |
| Sanya, Hainan | Early rice 27 |
Test method:
Stem and leaf is sprayed: after Oryza sativa L. 3 leaf 1 heart, the weeds 3-5 leaf phase, hand sprayer, 15 kilograms/667m of the amount of being watered2, adopt stem and leaf spraying even spraying.
Spread fertilizer over the fields: after Oryza sativa L. 2 leaf 1 heart, the weeds 2-3 leaf phase, mix fine sand or broadcast application.
Concrete test medicine and dosage, in Table 18, plot area 50 square metres, often process and repeat 4 times.After dispenser, 45 days investigation preventive effects are in Table 18, and rice safety implementations is in Table 19.
Table 18 field demonstration effect situation
Table 19 field demonstration rice safety implementations
Note: weed community type in each demonstration pilot project: public security: barnyard grass+Semen Euphorbiae+Herba Cyperi Difformis+Herba monochoriae vaginalis；Poyang: barnyard grass+Semen Euphorbiae+Herba monochoriae vaginalis；Changsha: barnyard grass+Semen Euphorbiae+Herba monochoriae vaginalis；Yingkou: barnyard grass+Herba monochoriae vaginalis+Sagittaria trifolia L. Var. Angusti-folia(Sieb.) Kitag.(Sagittaria sagittifolia L.)；Sanya: barnyard grass+Semen Euphorbiae+Herba Cyperi Difformis.
Through lot of experiments and exploration, the present invention is surprised to find that, described compositions removes grassy weed for rice terrace Seedling rear defence, have surprising, beyond thought potentiation, especially to barnyard grass, the grassy weeds such as Semen Euphorbiae, Herba Cyperi Difformis, the broad leaved weedses such as Herba monochoriae vaginalis have particularly evident potentiation, this potentiation shows more notable under low dosage, dosage can be reduced, and to rice safety, reduce the pollution to environment, and rationally composite reduce agricultural cost, to ALS, ACCase inhibitor resistant weed is efficient, there is good application prospect.
