Abstract
The invention relates to a special auxiliary for mesotrione. The special auxiliary comprises the following substances by mass percent: 0-80% of ether surfactant, 1-80% of phosphate ester surfactant and 0-80% of sulfonate surfactant, wherein the mass percents of the ether surfactant and the sulfonate surfactant are not zero at the same time. The invention further relates to a dispersible oil suspension prepared therefrom. The special auxiliary for mesotrione can be used for preparing 10-40% mesotrione dispersible oil suspension. After the phosphate ester surfactant is added into the mesotrione dispersible oil suspension, the storage stability and use efficacy of the mesotrione dispersible oil suspension are greatly improved.
Description
Technical field
The present invention relates to a kind of agricultural chemicals used additives, relate in particular to mesotrione special assistant, the invention still further relates to the mesotrione that contains this mesotrione special assistant and dispersible oil-suspending agent.
Background technology
Mesotrione is the new three ketones weed killer herbicide of Zeneca Nong Hua company exploitation, it is another three ketones weed killer herbicide kind of developing by sulphur humulone structural modification, its biologically active exceedes sulphur humulone more than 10 times, has more potentiality to be exploited with competitive, within 2000, registers in Europe.It starts in 2001 with trade name Callisto to sell in Germany and Austria, and because it is environmentally friendly, calendar year 2001, its single dose and mix preparation were sold in EU countries and the U.S. in 2002 by the approval of Environmental Protection Agency USA.Shenyang Chemical Engineering Inst in 2002 years, this kind is synthesized and in greenhouse and field carried out drug effect and safety research.
Mesotrione controlling object is that annual broadleaf weed+part grassy weed (broad-leaved preventive effect is better than to grass family) is mainly used in Control Weeds in Maize Field as Siberian cocklebur etc., and the weeds that sulfonylurea herbicide produced to resistance are effective.Mesotrione has very high activity of weeding to corn field weed, can effectively prevent and kill off the broadleaf weeds such as dayflower, piemarker, knotweed, acalypha copperleaf, lamb's-quarters, Amaranthus retroflexus, and the monocotyledon weeds such as lady's-grass, barnyard grass, green foxtail are also had to certain preventive and therapeutic effect.Use 3-5 days implants meristematic tissue of mesotrione to occur that yellow symptom causes withered spot thereupon, after fortnight, spread all over whole strain plant.There is faintly acid, in inoic acid soil, can tightly be adsorbed on organic substance; In neutrality or basic soil, exist to be difficult for absorbed anionic form.
Mesotrione can be degraded fast widely, and final metabolite is carbonic acid gas, and the half life period mean value in soil is 9 days, has fast degradation in soil, and the feature such as consumption is low.Mesotrione feature: 1, temperature on the activity of weeding impact of mesotrione very large (grass family barnyard grass) under 0 DEG C of condition, 150g/hm mesotrione is substantially invalid to barnyard grass; Under 25 DEG C of conditions, be 40% to barnyard grass preventive effect, show as blade albefaction, but continued growth; Under 35 DEG C of conditions, barnyard grass is had to good preventive effect, the albefaction of barnyard grass blade, wilting, progressively downright bad.2, precipitation affects is little, different time simulated rainfall after dispenser, found that rainfall in 0.5h after processing, on the herbicidal effect of mesotrione without impact, 1h rainfall after dispenser, on the herbicidal effect of mesotrione still without impact, the ability that mesotrione resistance of rainwater washing against be described by force or weeds very fast to the absorption of mesotrione.3, to corn safety.Mesotrione soil treatment or cauline leaf are processed the selection number of corn are greater than to 4 (by biologically active and the known mesotrione of safety experiment result to each corn variety ED10 >=600 or 800g/h, be 100 ~ 150g/hm to the ED90 of weeds), illustrate that it is good to the safety of corn.Under high dose, process, the symptom of chemical damage of corn is shown as to leaf portion albinism, because of the susceptibility difference of dissimilar corn, the degree of blade albefaction is also different, more responsive with sweet corn and pop corn.Mesotrione is under normal using dosage, to corn safety.Foreign study result shows, corn is because corn is slow to the infiltration rate of medicament to the resistance of mesotrione; Monocotyledon is as lower hundreds of times than broad leaved weed to the susceptibility of mesotrione in HPPD enzyme in wheat body; Corn can be degraded to mesotrione the compound of non-activity fast, particularly by the 4-hydroxylation of P450 catalysis.
Using method: (1) mesotrione soil treatment: in the time of 150g/hm, major part is reached to 90% for examination broad leaved weed preventive effect, to grassy weed preventive effect more than 80%.The biologically active of mesotrione is about 2 times of similar medicament sulphur humulone.(2) mesotrione cauline leaf processing: in the time of 100g/hm, can reach 90% to the preventive effect of broad leaved weed, the preventive effect of grassy weed is reached to 70%.The biologically active of mesotrione cauline leaf processing is about 3 times of similar medicament sulphur humulone.(3) mesotrione mixture atrazine: make up the drug effect of synergy mesotrione to grassy weed, can obviously improve the preventive effect to grassy weed after adding atrazine, reduce mesotrione consumption.
According to the requirement difference of using method or the drug effect that will reach, mesotrione can be made into and dispersible oil-suspending agent (OD) and two preparation varieties of aqueous suspension agent (SC).Dispersibling oil-suspending agent " OD " is the Oil-based suspension concentrate of the new release of FAO (Food and Agriculture Organization of the United Nation) (FAO) in recent years, claims again the Oil dispersion code of formulation.In CNS " GB/T 19378-2003 formulations of pesticide title and code ", there is not yet, the definition that FAO provides, be: active ingredient (may contain the active ingredient of other dissolvings) liquid preparation of stable suspersion in organic fluid, uses after dilute with water.In 15 kinds of formulations of pesticide that increase in the agricultural industry criteria NY/T 1667.2-2008 of the People's Republic of China (PRC) " agriculture chemical registration management terms " part 2 ' product chemistry ', awarding the definition that dispersibles oil-suspending agent (OD) is: the particulate of active ingredient and auxiliary agent energy stable dispersion thereof are in the liquid of non-water quality, and water is rare selects rear use.Suspending agent " SC " is the formulations of pesticide of exploitation in nearest 40 years, and growth momentum is good at present, has become one of important formulations of pesticide.The definition of suspending agent: non-water-soluble solid active ingredient and relevant auxiliary agent form the thickness suspension preparation of high degree of dispersion in water, use after dilute with water.Dispersible oil-suspending agent have good dispersion, stable performance, tackness good, to target synergistic effect obviously, drug effect performance more fully, be convenient to the advantages such as mechanically actuated; SC is environmentally friendly, there is no organic solvent, and safety easy to use is less demanding to dilution temperature and the hardness of water of water, high-load, low cost.
The product of current domestic agriculture chemical registration is mainly that 10%, 15% mesotrione dispersibles oil-suspending agent, 20%, 40% aqueous suspension agent; These products exist mesotrione easily to decompose in storage process at present, finally affect the result of use of product.
Summary of the invention
The present invention has overcome deficiency of the prior art, is to provide a kind of mesotrione special assistant, is had the safety of use, is improved the bin stability of mesotrione and the feature of result of use by the oil-suspending agent that dispersibles of its configuration.
Concrete technical scheme of the present invention is as follows:
A kind of mesotrione special assistant, comprises following material by mass percentage;
