Abstract

The invention provides a weeding composition containing oxadiargyl and simetryn, wherein the weight ratio of the oxadiargyl to the simetryn is 1: 20-20: 1. The composition can be used for preventing and removing weeds in paddy fields, can reduce the using amount of medicaments, reduce the harm to the environment and is beneficial to the generation of drug resistance of the weeds.

Description

Weeding composition containing oxadiargyl and simetryn
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing oxadiargyl and simetryn.
Background
Oxadiargyl is a novel oxadiazole nitrogen heterocyclic ring-containing pre-emergence contact-type selective broad-spectrum herbicide, and is mainly used for pre-emergence prevention and control of various annual gramineous weeds, cyperaceous weeds and broadleaf weeds in crops such as rice, sunflower, potatoes, beet, vegetables, orchards and the like. The product can be used for preventing and killing weeds of Echinochloa, Chenopodium, Amaranthus, herba Bidentis Bipinnatae, semen Euphorbiae, and brachypodium.
The simetryn belongs to sym-triazine herbicides and is a systemic conduction type selective pre-emergence soil treatment agent. The herbicide composition is suitable for preventing and killing barnyard grass, hairy euphorbia, potamogeton indica, rhizoma alismatis, edible tulip, mother grass, small arrowhead and other weeds in a rice field, is mixed with herbicide such as prosulfocarb, butachlor, Hezhuangzhuang and the like, and can expand the weed control spectrum. It can also be used for weeding in crop fields such as corn, soybean, wheat, peanut, cotton and the like.
In the weeding practice, the combination of two or more active ingredients is found to screen out the herbicide composition with synergistic action because the single agent can cause serious drug resistance of weeds after long-term use. The applicant finds, through search, that no report is provided in the prior art about the use of oxadiargyl and simetryn in a compounding manner.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a weeding composition which can obviously reduce the dosage of active ingredients, slow down the generation of drug resistance and has obvious synergistic action.
The technical scheme provided by the invention is as follows:
a weeding composition containing oxadiargyl and simetryn comprises the active ingredients of oxadiargyl and simetryn, wherein the weight ratio of the oxadiargyl to the simetryn is 1: 20-20: 1.
The weeding composition disclosed by the invention is preferably prepared from oxadiargyl and simetryn in a weight ratio of 1: 5-5: 1 and 1: 20.
The weeding composition is characterized in that the weight percentage of the active ingredients is 1-85%. The dosage forms of the weeding composition which can be prepared into wettable powder, water dispersible granules, missible oil and granules.
The weeding composition is used for preventing and controlling weeds in paddy fields. The composition is preferably used for preventing and controlling annual weeds such as monochoria vaginalis, gynura bicolor, cyperus rotundus and barnyard grass in the paddy field.
Compared with the prior art, the invention has the following beneficial effects:
the oxadiargyl and simetryn belong to different classes of herbicides, have different action mechanisms, have obvious synergistic action after being mixed, can improve the control effect, and are beneficial to overcoming and delaying the generation of drug resistance of weeds.
The composition has excellent weeding effect on annual weeds in the paddy fields, and can be used for preventing and controlling various weeds in the paddy fields.
Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Example 1: indoor toxicity determination method of oxadiargyl and simetryn on monochoria vaginalis
Test subjects: monochoria vaginalis seeds (field collection, laboratory preservation)
The test method comprises the following steps: a greenhouse potting method is adopted. Adding test soil (without agent treatment) into a flowerpot, adding water until the soil is completely wet, and respectively sowing the vernalized monochoria vaginalis seeds into the flowerpot. After sowing for 24 hours, soil spraying treatment is carried out, each treatment is repeated for 4 times, and blank control is additionally arranged. Culturing in a greenhouse after treatment, periodically supplementing water in a bottom irrigation mode, and keeping the soil humidity of 100%. Spraying equipment: ASS-1 type pesticide spraying system. The fresh weight of each treated weed was calculated after 14 days. The data was analyzed using the sps software to calculate the ED50 value.
And (3) measuring the combined toxicity of the agents, calculating the synergistic coefficient (SR) of the mixed agents by using a Wadly method, and evaluating the combined action type of the mixed agents. SR — compound theory ED 50/compound found ED 50.
When SR is less than 0.5, the mixed medicament has antagonism; when SR is not less than 0.5 and not more than 1.5, the mixed medicament has additive effect, and when SR is more than 1.5, the mixed medicament has synergistic effect.

Figure BDA0002403634050000031
Figure BDA0002403634050000041
As can be seen from the data recorded in Table 1, the ratio of oxadiargyl to simetryn is in the range of 20: 1-1: 20, and the composition has a good control effect on the monochoria vaginalis. The weight ratio of the oxadiargyl to the simetryn is in the range of 5: 1-1: 5 and 1: 20, the SR value of more than 1.5 shows a synergistic effect, the rest weight ratios show an additive effect, the most preferable weight ratio of the oxadiargyl to the simetryn is 1: 5, and the SR value is 1.88, so that the composition has a remarkable synergistic effect, can effectively improve the control effect, and can reduce the dosage of active ingredients.
Example 2Oxadiargyl and simetryn field control effect on weeds
Test subjects: weeds in paddy field (monochoria vaginalis, potamogeton mukul, sedge heterotypic, barnyard grass)
The test method comprises the following steps: the test result shows that the soil is flat and the fertility is uniform. The pH value of the soil is about 6.8, and the organic matter content is about 17.5 g/kg. Sowing in 10 days after 6 months, and soaking the rice seeds for accelerating germination. Transplanting in 7 months and 8 days, and managing according to a conventional method. And applying the pesticide 5 days before transplanting the rice by a pesticide soil method. A blank control treatment area is arranged and repeated for 3 times, and the cells are arranged in random blocks. And (5) surveying weeds in each plot 14 days after the pesticide application, and calculating the fresh weight control effect.
Test agents:
① 25% oxadiargyl dispersible oil suspension (commercially available)
② 25% wettable SiCaojing powder (commercially available)
③ 30% propisochlor wettable powder (formulation: oxadiargyl 5%, simetryn 25%, sodium dodecyl sulfate 6%, calcium lignosulfonate 4%, attapulgite 4%, and kaolin to make up 100%)
