Abstract
The invention discloses a compound weeding composition containing monosulfuron ester and application thereof. The binary weeding composition adopts the monosulfuron ester and the isoproturon which have different weed control spectra and complementary advantages and disadvantages to be compounded, and the combined use of the monosulfuron ester and the isoproturon delays the generation of the drug resistance of crops, so that the binary weeding composition has ideal use effects: broad herbicide controlling spectrum, quick effect, high efficiency, low toxicity, low residue, safety and environmental protection, can reduce the pesticide dosage and the pesticide residue, has good environmental compatibility, is safe to people and livestock, and the like, and is a high-quality wheat crop chemical herbicide. Because the use content of the effective active ingredients is reduced, the pesticide residue is reduced on the premise of improving the pesticide effect, the safety to wheat and succeeding crops is higher, and the possibility that the pesticide generates residual toxicity to people and livestock is avoided.
Description
Technical Field
The invention relates to a weeding composition, and in particular relates to a compound weeding composition containing monosulfuron ester and application thereof.
Background
Wheat is one of main crops in China, with the continuous expansion of the planting area of wheat, the wheat field is increasingly serious in weed damage, and whether the wheat can effectively control the weed damage in the wheat field and stabilize the high yield of the wheat becomes one of the main subjects of the research of modern agricultural herbicides.
The wheat field herbicides in the current market have the problems of narrow weed control spectrum and incapability of effectively weeding broadleaf weeds and gramineous weeds in the field at the same time.
Monosulfuron ester (code # NK94827) is a sulfonylurea herbicide which is self-developed after being industrialized by pesticide national engineering research center (southern opening university) followed by monosulfuron (# NK 92825). The chemical structural formula of the monosulfuron ester is as follows:
as an ultra-efficient innovative pesticide with independent intellectual property rights in China, the monosulfuron ester has good control effect on weeds in wheat fields, is very safe for most common aftercrop corns in the wheat fields, and has the characteristic of being obviously superior to other sulfonylurea compound herbicides. However, the monosulfuron ester single dose is not sensitive to some weeds.
Isoproturon (isoproturon), chemical name: 3-p-cumyl-1, 1-dimethylurea; n' - (4-isopropylphenyl) -N, N-dimethyl urea, wherein the chemical structural formula of isoproturon is as follows:
isoproturon is a substituted urea herbicide which selectively interferes with the photosynthesis of weeds, and can be used before and after germination. After the agent is absorbed by the roots of plants, the agent is transported and accumulated in leaves to inhibit photosynthesis, so that weeds are died.
The herbicides of the above different chemical compositions vary in their herbicidal capabilities and ranges. When the herbicide with a single effective component is used in agricultural production, the occurrence of weeds in wheat fields cannot be completely and effectively controlled due to the influence of factors such as weed control range, weed control capability, resistance and the like, the weed eradication effect is greatly reduced, and residual toxicity to current crops or afterreap crops is easily caused by large water solubility, too short field lasting period, excessive use amount or uneven application of some herbicides.

Annual broad-leaved weeds such as descurainia sophia, shepherd's purse and chickweed and annual gramineous weeds such as bluegrass, alopecurus, wild oat, beckmelon syzigachne and hardwood are selected as tested weeds.
In an area of 0.04m2The pot is filled with a certain amount of soil to 3/4 deep in the pot, and then clear water is poured from the top of the pot to ensure that the soil is completely wet to a saturated state. 100 weed seeds to be tested are uniformly sown on the soil surface of the pot, and the soil is covered with 0.5-2 cm of fine soil according to the size of the seeds and then is cultured in a greenhouse. After 24 hours, pouring 10ml of liquid medicine quantitatively in each pot, repeating the treatment for 4 times in each treatment setting, taking the treatment without the medicine as a blank control, placing the treated test material in a greenhouse for culturing, regularly observing the growth condition of the target weeds, and keeping a water layer of 1-2 cm in each treatment pot all the time during the test. And after 21d, visually observing target damage symptoms and growth inhibition conditions, weighing the fresh weight of the overground part, and calculating the fresh weight control effect (%).
The evaluation of the synergistic effect shown in the mixed application of two or more herbicidal active ingredients was determined based on the Colby's method described in "marketing synergistic and antibiotic Responses of Herbicide combinations" (Weeds 15/1(1967), s.r. Colby) as follows:
in the formula:
a is the survival rate or fresh weight survival (%) of the target weeds when the active compound A is used in mg/ha or mppm concentrations.
B is the survival rate or fresh weight survival (%) of the target weeds when using the active compound B in the amount ng/ha or at the concentration nppm.
C is the survival rate or fresh weight survival (%) of the target weeds when the active compound C is used in an amount of hg/ha or at a concentration of hpppm.
n is the number of the mixed weeding active ingredients.
E0Is the theoretical value of the survival rate or fresh weight survival (%) of the target weeds when the active compounds A, B and C are used in amounts of m, n, hg/ha or in concentrations of m, n, hpppm in combination.
E is the actual value of the survival rate or the fresh weight survival (%) of the target weeds when the active compounds A, B and C are used in amounts of m, n, hg/ha or in concentrations of m, n, hpppm in combination.
If the actually observed survival rate or the fresh weight survival rate of the target weeds is less than the theoretical survival rate or the fresh weight survival rate of the target weeds, E0E > 0, the composition exhibits a synergistic effect with unexpected synergistic effects.
