Description
Technical field
The invention belongs to pesticide field, and in particular to a kind of herbicide composition for paddy fields and its application.
Background technology
Chemical weed control is means the most economical and effective during farmland weed is prevented and kill off, but uses list for a long time continuous high dose
The chemical herbicide of one kind or the single mode of action, the problems such as easily causing weeds resistance and resistance evolution.Herbicide chemical combination
The reasonable compounding or mixture of thing have expand weeds spectrum, improve preventive effect, delay weeds drug resistance and it is drug-fast generation with
The advantages that development, it is one of maximally efficient method to solve the above problems.
P _ Hydroxyphenyl pyruvic acid dual oxide enzyme (HPPD) is after acetyl-CoA carboxylase (ACCase) inhibitor, acetyl breast
The another class novel herbicidal found after acid enzyme (ALS) inhibitor and proporphyrinogen oxidase (Protox) inhibitor etc.
Agent.The action character of HPPD inhibitor is the activity of weeding for having wide spectrum, be can be used before bud and after bud, after albefaction occur in weeds
It is dead.Though its symptom is extremely similar to the effect symptom of carotenoid biostatic agent, its chemical constitution feature such as polarity and electricity
There is obvious difference with known carotenoid biostatic agent from degree.
HPPD inhibitor class herbicide Weed Resistance risk is significantly less than ACCase inhibitor, and with conventional ACCase
Cross resistance caused by target resistance is not present in other mechanism of action such as inhibitor, ALS inhibitor.
Herbicide-safener (Safener), also referred to as antidote (Antidote) or protective agent (Protectant), are to have
The chemical substance of special performance.Herbicide-safener is on the premise of herbicide is not influenceed to target weeds activity, there is selection
Cover crop exempts from herbicide damage on ground, so as to strengthen tolerance of the crop to herbicide, peace of the increase herbicide to crop
Quan Xing.Research of the states such as the U.S., Germany, Switzerland, Japan, Canada, Russia, South Korea and Hungary to herbicide-safener compared with
More, China starts late, and just starts 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
Derivative species, oxazoles, thiazole and other heterocyclic compounds, ketone and its derivative etc.；It can be divided into by structure：Naphthoic acid anhydride, two
Chloroacetyl amine, oxime ethers, heterocyclic, sulfonylureas (amine) class, plant growth regulator class, classes of herbicides and bactericide class etc.；
It can be divided into by the mode of action and action principle：Mating type, breakdown type, antagonism type, offset-type etc..
With the extensive use of herbicide, herbicide damage problem continuously emerges, and exists to herbicide-safener and compels to be essential
Ask.Herbicide-safener include 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 water
Rice, sorghum, corn, wheat, rye, cotton, soybean etc..
The herbicide of rice terrace application at present mainly has dichloro quinolinic acid, bispyribac-sodium, penoxsuam, cyhalofop-butyl etc. few
Number kind.This several herbicides uses for many years on rice, and weeds resist to penoxsuam, bispyribac-sodium, cyhalofop-butyl
Sex chromosome mosaicism starts to highlight, and especially produces obvious resistance to barnyard grass in the current main flow herbicide of live rice region, and moleplant seed is to only
One herbicide-the cyhalofop-butyl for being used for rice registration also produces notable resistance.Therefore safe, herbicide controlling spectrum is needed badly in production
Extensively, it can solve the problem that the kind of resistant weed problem.
The content of the invention
To solve the above-mentioned problems in the prior art, the present invention provides a kind of herbicide composition for paddy fields and its should
The weed problems such as barnyard grass in rice terrace, moleplant seed, nutgrass flatsedge can be effectively prevented and kill off with, said composition, is had and is expanded herbicide controlling spectrum, reduces

C, field demonstration
Utilize embodiment 1) -22) made from herbicidal composition prevent and kill off paddy field weed experiment.
2014 in Hubei public security, Jiangxi Poyang, Hunan Wangcheng, Liaoning Shenyang, the experiment of the rice belt 25 of Sanya, Hainan 5
Point carries out exemplary promote and tested.Different demonstration area rice varieties refer to table 17.
The different demonstration area rice varieties situations of table 17
| Demonstration area | Rice varieties |
| Hubei public security | The province of the Yuan Dynasty is live |
| Jiangxi Poyang | Two excellent 287 |
| Hunan Wangcheng | Huang Huazhan |
| Liaoning Yingkou | Logical round-grained rice 89 |
| Sanya, Hainan | Early rice 27 |
Test method：
Cauline leaf is sprayed：After the heart of 3 leaf of rice 1, the weeds 3-5 leaf phases, hand sprayer, 15 kilograms/667m of the amount of being watered2, use
Cauline leaf spraying even spraying.
Spread fertilizer over the fields：After the heart of 2 leaf of rice 1, the weeds 2-3 leaf phases, fine sand or broadcast application are mixed.
Specific test medicine and dosage are shown in Table 18, and 50 square metres of plot area, often processing is repeated 4 times.Adjust within 45 days after dispenser
Look into preventive effect and be shown in Table 18, rice safety implementations are shown in Table 19.
The field demonstration effect situation of table 18
The field demonstration rice safety implementations of table 19
Note：Weed community type in each demonstration pilot project：Public security：Barnyard grass+moleplant seed+difformed galingale herb+Monochoria vaginalis；Poyang：Barnyard grass+
Moleplant seed+Monochoria vaginalis；Changsha：Barnyard grass+moleplant seed+Monochoria vaginalis；Yingkou：Barnyard grass+Monochoria vaginalis+angustifolia arrowhead herb；Sanya：Barnyard grass+a thousand pieces of gold
Son+difformed galingale herb.
By lot of experiments and exploration, it is an unexpected discovery of the invention that the composition prevents and kill off grass for rice terrace after seedling
Section weeds, there is surprising, unexpected synergistic effect, especially to the grassy weeds such as barnyard grass, moleplant seed, abnormal shape
The broad leaved weedses such as nutgrass flatsedge, Monochoria vaginalis have particularly evident synergistic effect, and this synergistic effect shows more under low dosage
Significantly, it can reduce dosage, and to rice safety, reduce the pollution to environment, and rationally compounding reduces agricultural cost, it is right
ALS, ACCase inhibitor resistant weed are efficient, have good application prospect.
