Abstract

The invention discloses a weeding composition for a sugarcane field. The weeding composition comprises weeding active components such as imazapic and halosulfuron-methyl and the balance herbicide auxiliary agents. A mass part ratio of imazapic to halosulfuron-methyl is 20: 1 to 1: 20. Through combination of the imazapic and halosulfuron-methyl, obvious Cyperus rotundus synergism is obtained. According to the existing herbicide technology, the weeding composition can be processed to form water dispersible granules.

Description

A kind of Caulis Sacchari sinensis field weeding composition
Technical field
Composition pesticide according to the present invention, active component is AC 263222 and halosulfuronmethyl, for preventing and treating Caulis Sacchari sinensis Field Rhizoma Cyperi weeds.
Background technology
Rhizoma Cyperi, the perennial sedge weed that a kind of sugarcane field is often sent out, by underground tuber, rhizome, bulb and the aerial stem of plant Leaf forms, and it has surprising fertility, and tuber, rhizome, bulb and seed can be bred.In the season of growth it is within one week about Can grow and emerge, new tuber can be produced within about 20 days, not only tuber be such bulb can also, and when condition is suitable, plant Son and rhizome also can germinate and produce new plant and tuber.
About 23,000,000 mu of China's sugarcane acreage, mainly distribution Guangxi, Guangdong, Yunnan, Hainan, occur according to on-site inspection Rhizoma Cyperi occurs population to expand year by year in China Caulis Sacchari sinensis main producing region Guangxi, Guangdong, and Rhizoma Cyperi prevention and control success or failure have a strong impact on Caulis Sacchari sinensis and produce Amount.
Chemical method weeding is one of Main Means of weeds control, is easily caused using single kind compound herbicide Weeds develop immunity to drugs.
AC 263222, English name：Imazapic, by suppressing the acetolactate synthestase of plant, stops side chain ammonia Base acid such as L-Valine, leucine, the biosynthesiss of isoleucine, thus destroying the synthesis of protein, does anti-DNA synthesis and cell Division and growth, ultimately cause plant dead.It is a kind of efficient, new herbicides of wide spectrum, weeds can not only be killed well Aerial partss plant, and the root to underground part and subterraneous stem also have stronger preventive effect.
Halosulfuronmethyl, English name：Halosulfuron-methyl, sulfonylurea herbicide, inhaled by the root of weeds It is transmitted to after receipts in plant body, the synthesis of hindered aminoacid, promptly the suppression growth of weeds leaves and stemses and the stretching, extension of root, so Completely withered afterwards.
The present inventor has made intensive studies to AC 263222 and halosulfuronmethyl, screens examination in substantial amounts of formula indoor Test with field medicine effect test on the basis of, find that AC 263222 and halosulfuronmethyl carry out mixture, in certain mixed ratio In the range of obvious potentiation is shown to Rhizoma Cyperi, after further study, complete the present invention.
Content of the invention
It is an object of the invention to poor to farmland weed effect in solution prior art, easily develop immunity to drugs problem, A kind of safe efficient, environmental protection is provided, is conducive to the Herbicidal combinations that farmland weed is administered.
It is a further object of the present invention to provide this Herbicidal combinations is used for sugarcane field Rhizoma Cyperi control of weeds.
Technical scheme：A kind of Caulis Sacchari sinensis field weeding composition, effective ingredient is AC 263222 and halosulfuronmethyl, first imidazoles The mass ratio of nicotinic acid and halosulfuronmethyl is 20:1～1:20, AC 263222 and halosulfuronmethyl quality summation are in compositionss In mass number percentage ratio be 10%～80%, remaining be insecticides adjuvant.
Herbicidal combinations of the present invention can be assisted from suitable pesticidal preparations according to well known to a person skilled in the art method Composition, can be processed into the application forms use in the suitable agricultural production such as suspending agent, water dispersible granules.
Used in the present composition pesticide auxiliary element include solvent, dispersant, stabilizer, emulsifying agent, antifreezing agent, Thickening agent etc. and other be beneficial to effective ingredient known substance that is stable in the formulation and playing drug effect, be all in pesticidal preparations often With or allow the various composition using, be not particularly limited, concrete composition and consumption pass through simple test according to recipe requirements Determine.
Product described in the invention can be provided in the form of finished product preparation, and that is, in compositionss, each material is blended, group The composition of compound can also the form of single dose provide, and is directly mixed in tank or bucket using front, dense required for being then diluted to Degree.
The frequency of administration of the present composition and amount of application change and change with weather condition and crop condition, can pass through Reach the purpose of preventing and treating using suitable dosage form.
The present composition is used for preventing and treating sugarcane field Rhizoma Cyperi weeds, compared with prior art, beneficial effects of the present invention It is：1st, there is obvious potentiation, improve prevention effect；2nd, reduce Pesticide use amount, decrease the pollution to environment With reduce cost；3rd, weeds are delayed to generation compound resistance.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention are more short and sweet, present invention specific examples below Illustrate, but the present invention is only limitted to absolutely not these examples.Described below is only the preferable embodiment of the present invention, is used only for retouching State the present invention it is impossible to be interpreted as limiting the scope of the present invention.It should be pointed out that all the spirit and principles in the present invention it Interior done any modification, equivalent and improvement etc., should be included within the scope of the present invention.Therefore, the present invention The protection domain of patent should be defined by claims.
Embodiment 1：Bioassay test
Test material：Rhizoma Cyperi (scientific name：Cyperus rotundus), tuber joins village by Huidong County of Guangdong Province Ren Shan town five Collection.
Test apparatuses：Controlled illumination box；POTTER precision laboratory spray tower；Electronic balance (sensibility reciprocal 0.1mg)；Micro- Amount liquid-transfering gun etc..
Test method：In the built-in quantitative soil of porcelain alms bowl of high 6cm, diameter 9cm, by 15 sowings of target Rhizoma Cyperi daughter root block in porcelain In alms bowl, it is placed on warm indoor cultivation after the fine earth of lid 2～3cm, treats that target weeds length carries out stem and leaf spraying treatment, every porcelain alms bowl to 5cm Quantitative spray 1ml, often processes 4 repetitions, and the process setting without medicament is comparison, after process, examination material is placed in warm indoor cultivation, determines Phase observes the growing state of target weeds, range estimation target damage symptoms and growth inhibited situation after 15d, and claims weeds fresh weight, with Target fresh weight inhibition evaluates the toxicity action to target weeds for the medicament.
Range estimation target damage symptoms and growth inhibited situation after test process 15d, and claim aerial partss fresh weight, calculate fresh weight Suppression ratio (%).
Herbicide associated form (NY/T 1155.7-2006) is evaluated according to Gowing method, its formula is as follows：
E0X Y XY/100
In formula, X is active components A with certain dosage fresh weight inhibition to target weeds when alone；Y exists for active component B Fresh weight inhibition to target weeds when certain dosage is alone；E0For when active components A, bis- kinds of pharmacy mix of active component B to target The theoretical value of mark weeds fresh weight inhibition；E is when active components A, two kinds of pharmacy mix of active component B, target weeds fresh weight to be pressed down The measured value of rate processed.
Evaluation criterion：As E E0During ＞ 10%, it is expressed as potentiation；As 10%≤E E0When≤10%, show as phase Plus effect；As E E0During ＜ 10%, show as antagonism.
All test datas are all analyzed using DPS v14.10 statistical software.
Table 1 shows, AC 263222 and halosulfuronmethyl combine, E E0＞ 10%, is expressed as potentiation, first imidazoles cigarette Acid and halosulfuronmethyl combination are rational.
