Abstract
The invention relates to a method for preventing and controlling creeping oxalis by taking diuron as an effective component. The method adopts the technical scheme that diuron is taken as the effective component, and tank-mix adjuvant is taken as required and used for preventing and controlling creeping oxalis; the diuron can be processed into wettable powder or water dispersible granules and separately used for preventing and controlling creeping oxalis or weeds; or the tank-mix adjuvant is taken as required for improving the prevention and control effect. The invention has the characteristics of long duration, good control effect, and the like; and by using the method, the control effect can be up to 85 percent, the effective period can be up to 2 months, and the harm of the creeping oxalis to the crops all seasons can be basically eliminated.
Description
Technical field
The present invention relates to the agricultural herbicide field, especially a kind of is the active ingredient method for preventing and controlling creeping oxalis by taking with diuron
Background technology
In recent years, creeping oxalis farmland running to weeds, ground such as Guangxi are serious, especially many villages sugarcane field window-box oxalis Herba Gynostemmatis on ground such as Nanning, Liuzhou is bloomed, and therefore, won the another name of " sour mew team ".According to the weeds expert introduction, window-box oxalis has another name called big tart flavour grass, be commonly called as sour mew, it is mainly bred by underground bulb, a scale is reached maturity and can be generated the 40-60 sheet, and breeding development diffusion velocity is very fast, and more and more fiery trend is arranged at present, as can not effectively preventing and kill off, with the main malignant weed group of procreation for farmland after the rhizome of nutgrass flatsedge.Creeping oxalis mainly is to win honour for, strive fertilizer with crop, the sprouting that has influence on the new plant cane seedling at sugarcane field be unearthed and stubble cane send out strain rate and tillering capacity, thereby remote-effects are to sugarcane yield.The weed killer herbicide that sugarcane field is commonly used have only the preventive effect about 10% substantially, and had only about a week lasting period to the non-constant of oxalic effect now.
Summary of the invention
Technical problem to be solved by this invention is a kind of new weed killer herbicide of development, prevents and kill off the malignant weeds such as creeping oxalis in crop fields such as sugarcane.
For this reason, the applicant is on the basis of mass efficient composition screening, and it is better to control window-box oxalis effect to filter out diuron, has characteristics such as lasting period length, preventive effect height.But consider that when independent use diuron was prevented creeping oxalis, because creeping oxalis has wax coat, liquid waste was serious, so consideration is passed through the mixed auxiliary agent raising of a bucket preventive effect, saves amount of liquid medicine, is protected environment.
Diuron
CAS 330-54-1
The Chinese diuron
English name Diuron;
Another name N-(3, the 4-dichlorophenyl)-N ', N '-dimethyl urea
Molecular formula C
9H
10C
12N
2O
Structural formula
The pure product of outward appearance and proterties are white odorless crystal
Molecular weight 233.10 vapour pressures 0.04 * 10-6kPa (50 ℃)
The pure product of physicochemical property this product are the colourless crystallization solid, and 158～159 ℃ of fusing points are soluble in hot alcohol, in the time of 27 ℃ in acetone solvability be 5.3%, be dissolved in ethyl acetate, ethanol and hot benzene slightly.Water insoluble, the 42ppm when solvability in water is 25 ℃.Solvability is low in hydro carbons.To oxidation and hydrolysis-stable.
The technical solution used in the present invention is:
With the diuron is active ingredient, and the mixed auxiliary agent of bucket is used for preventing and kill off creeping oxalis as required.
With the diuron is active ingredient, diuron can be processed into wetting powder as required, or water dispersible granules; Be used for preventing and kill off creeping oxalis or weeds separately.
The mixed auxiliary agent of bucket is to improve preventive effect as required.
Both can be used to anti-creeping oxalis, also can be used to other farmland weeds such as anti-eleusine indica.
Described auxiliary agent is vegetable oil or modification vegetable oil, mineral oil, organosilicon or surfactant etc.
Described vegetable oil refers to cottonseed oil, rape oil or soybean oil; Modification vegetable oil such as esterification soybean oils esterified vegetable oil; Mineral oil such as paraffin oil, diesel oil, kerosene or machine oil etc.
Described surfactant is meant calcium lignosulfonate, draws back powder, lauryl sodium sulfate, naphthalene sulfonic acid formaldehyde condensation polymer, phenethyl phenol polyethenoxy ethers (as the newborn 603# of farming), calcium dodecyl benzene sulfonate (as the newborn 500# of farming), increase outstanding agent auxiliary agents such as (as CMC).
The present invention utilizes the Hill reaction in the diuron inhibition photosynthesis, the required illumination of this medicine kill plants.Make the weeds that are injured begin to fade from blade tip and edge, withered to full leaf eventually, can not make nutrient, hungry and dead.Have characteristics such as lasting period length, preventive effect height.Can reach more than 85% with the method preventive effect that the present invention introduced, the lasting period can reach more than 2 months, can eliminate the harm of creeping oxalis to whole season crop substantially.
