Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a triacontanol-containing weeding pesticide composition.
Background
Spraying chemical pesticide is an effective means for effectively controlling weeds in agriculture, but long-term use of single chemical pesticide easily causes drug resistance of weeds, so that the control effect of the chemical pesticide on the weeds is reduced.
Triacontanol is a natural long carbon chain plant growth regulator, has the chemical name of n-triacontanol, and is a natural biological product purified and extracted from bee wax. The triacontanol can be absorbed by stems and leaves of plants to promote the growth, differentiation and development of the plants, has the effects of promoting the absorption of mineral elements, promoting cell division, increasing the content of chlorophyll, promoting the differentiation of rooting leaves and flower buds, increasing tillering and the like, and has better yield increase effect on rice, cotton, wheat, soybeans, tobacco, flowers, fruit trees and the like.
In the prior art, no weeding effect is reported when triacontanol is used alone, but when triacontanol is mixed with glyphosate, the control effect of the mixed agent on weeds is better than that of the glyphosate used alone, and the application amount of the glyphosate can be reduced. In addition, application number CN202010865455.9 also discloses a herbicide composition containing triacontanol and a preparation method and application thereof, and particularly discloses that when triacontanol and cyhalofop-butyl, penoxsulam or isooctyl fluorocloxate are compounded, the herbicide composition has a synergistic effect on weed control and improves the weeding efficiency.
Disclosure of Invention
The invention aims to provide a triacontanol-containing weeding pesticide composition to solve the problem of long-term use of a single chemical agent.
In order to achieve the purpose, the invention provides the following technical scheme:
a weeding pesticide composition containing triacontanol, the active ingredient of which is compounded by triacontanol and glufosinate-ammonium or glufosinate-ammonium, the triacontanol is 0.1 percent of triacontanol microemulsion; the glufosinate-ammonium is a 10% glufosinate-ammonium aqueous solution; the refined glufosinate-ammonium is 20% of a refined glufosinate-ammonium soluble agent.
Preferably, the mass ratio of the triacontanol to the glufosinate-ammonium is 1-9: 20-1.
Preferably, the mass ratio of the triacontanol to the refined glufosinate-ammonium is 1-20: 30-1.
The invention also provides application of the weeding composition in preventing and removing broadleaf weeds, gramineae weeds and cyperaceae weeds.
Compared with the prior art, the invention has the following beneficial effects:
when the triacontanol and the glufosinate-ammonium or the refined glufosinate-ammonium are compounded, the mixed preparation shows obvious weed control effect. Particularly, the mass ratio of triacontanol to glufosinate-ammonium is 7: when 1, the EC50 value of the mixed preparation on weed purslane is 14.93 mg/L; the mass ratio of triacontanol to refined glufosinate-ammonium is 1: when 5, the EC50 value of the mixture for the weeds barnyard grass is 10.14 mg/L; the triacontanol can enhance the weed control effect of the glufosinate-ammonium or the refined glufosinate-ammonium, reduce the application amount of the glufosinate-ammonium or the refined glufosinate-ammonium and reduce the pollution to the environment.
Detailed Description
The technical solutions of the present invention are described in detail below, and it is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples: indoor bioactivity test after triacontanol compounding
The tested weeds: herba Portulacae and Echinochloa crusgalli
Reagent to be tested: 0.1% triacontanol microemulsion (Hongtian Biochemical Co., Ltd., Guangxi Guilin city), 10% glufosinate solution (Nanning Taidafeng Biotech Co., Ltd.), 20% glufosinate-ammonium soluble solution (Guangxi agricultural science Co., Ltd.);
the test method comprises the following steps: (refer to' NY/T1155.4-2006 indoor bioassay Standard for agricultural chemicals herbicide part 4: spray method of foliage and stems in the Activity assay)
1. The test reagents are set into a plurality of groups of proportions, and each single reagent and the mixture of the proportions are set into 6 gradient mass concentrations for standby according to an equal proportion method.
2. Loading the soil to 4/5 of a pot, completely wetting the soil by adopting an infiltrating irrigation mode at the bottom of the pot, then uniformly spreading the weed seeds to be tested on the surface of the soil, covering the soil, then transferring the weed seeds to a greenhouse for conventional culture, thinning and fixing the weeds after the weeds to be tested emerge, and ensuring that the density of the weeds is 150 plants per square meter.
3. Spraying weeds at the 4-6 leaf stage by using a stem leaf spraying method, setting 4 times of treatment for each treatment, setting clear water as a blank control, and transferring the weeds into a greenhouse for continuous culture after the treatment.
4. Regularly observing the growth condition of the tested weeds in each treatment, investigating and recording the number of surviving weed plants 14d after the treatment, and calculating the fresh weight control effect of each treatment according to investigation data;
5. adopting DPS software to make data statistical analysis, using agent concentration logarithmic value and control effect logarithmic value to make regression analysis, calculating EC of every agent50The co-toxicity coefficient (CTC value) of the mixture was calculated according to the Sun Yunpei method.
The calculation method comprises the following steps:
results and analysis:
TABLE 1 toxicity assay results for portulaca oleracea by recombination of triacontanol and glufosinate-ammonium
Note: "- -" indicates no inhibition.
As can be seen from Table 1, triacontanol alone had no control effect on Portulaca oleracea, a weed. However, after triacontanol and glufosinate-ammonium are compounded for use, the mixed preparation shows obvious control effect on portulaca oleracea, and particularly, the mass ratio of triacontanol to glufosinate-ammonium is 7: when 1, the EC50 value of the mixed preparation on weed purslane is 14.93 mg/L; namely, when triacontanol and glufosinate-ammonium are compounded according to a certain mass ratio, the weed control effect of glufosinate-ammonium can be enhanced.
TABLE 2 toxicity test results of compounding triacontanol and glufosinate-ammonium for barnyard grass
Note: "- -" indicates no inhibition.
As is clear from Table 2, triacontanol alone had no controlling effect on the weeds barnyard grass. However, after the triacontanol and the refined glufosinate-ammonium are compounded for use, the compound shows obvious control effect on the cockspur grass, and particularly, the mass ratio of the triacontanol to the refined glufosinate-ammonium is 1: when 5, the EC50 value of the mixture for the weeds barnyard grass is 10.14 mg/L; namely, when triacontanol and the refined glufosinate-ammonium are compounded according to a certain mass ratio, the weed control effect of the refined glufosinate-ammonium can be obviously enhanced.
In conclusion, when the triacontanol and the glufosinate-ammonium or the glufosinate-ammonium are compounded, the mixed preparation shows obvious weed control effect, which shows that the triacontanol can enhance the weed control effect of the glufosinate-ammonium or the glufosinate-ammonium, the application amount of the glufosinate-ammonium or the glufosinate-ammonium can be reduced, and the environmental pollution is reduced.
