Abstract
The invention provides a weeding composition containing oxadiargyl and carfentrazone-ethyl, wherein the weight ratio of the oxadiargyl to the carfentrazone-ethyl is 5-10: 0.5-1.5. The composition has obvious synergistic effect, can reduce the use amount of medicaments, reduce the harm to the environment and is beneficial to the generation of weed drug resistance.
Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a weeding composition containing oxadiargyl and carfentrazone-ethyl.
Background
Oxadiargyl is a cyclic imine selective contact-type herbicide and is mainly used for weeding in rice transplanting fields. The agent acts primarily through absorption by contact sensitive weed sprouts. Has the advantages of high efficiency, broad spectrum, low toxicity, no influence on the succeeding crops and the like. In recent years, the application range of the medicament is expanded abroad, and the medicament is registered in the field of crops such as sugarcane, beans, potatoes, watermelons, lettuce, shallots, leeks, garlic, cabbage, cauliflower, tomatoes and the like. The company registers and registers a raw oxadiargyl drug and a preparation, such as 96% of the raw oxadiargyl drug (PD20141453), 80% of oxadiargyl water dispersible granules (PD20150332) and 10% of oxadiargyl missible oil (PD 20184165).
Carfentrazone-ethyl is a triazolinone herbicide developed by the company meigumei (FMC). Is mainly used for preventing and killing broadleaf weeds and nutgrass flatsedge and has excellent control effect. The company registers and registers 90% of carfentrazone-ethyl technical material (PD20140179), 40% of carfentrazone-ethyl water dispersible granules (PD20132070) and 12% of clenbuterol dispersible oil suspending agent (PD 20150793).
In weeding practice, the single agent is used for a long time, so that the weeds generate serious drug resistance, the application dosage of the active ingredients needs to be increased for achieving better control effect, the environment is seriously polluted, and the food safety is threatened.
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 carfentrazone-ethyl comprises active ingredients including oxadiargyl and carfentrazone-ethyl, wherein the weight ratio of the oxadiargyl to the carfentrazone-ethyl is 5-10: 0.5-1.5.
The weight ratio of oxadiargyl to carfentrazone-ethyl of the weeding composition is 6-8: 0.8-1.2.
The weeding composition also comprises agriculturally acceptable auxiliary agents, and the weight percentage of the active ingredients is 5-75%.
The weeding composition can be prepared into dosage forms of wettable powder, water dispersible granules, dispersible oil suspending agents, emulsion in water, missible oil and granules.
The weeding composition provided by the invention is used for preventing and controlling crop weeds. Preferably used for the control of annual or perennial weeds in paddy fields; it is preferably used for preventing and treating gramineae, broadleaf and nutgrass flatsedge.
Compared with the prior art, the invention has the following beneficial effects:
the weeding composition disclosed by the invention is composed of different active ingredients, has an obvious synergistic effect after being mixed, improves the control effect, and is also beneficial to overcoming and delaying the generation of drug resistance of weeds.
The composition of the invention is mixed with the pesticide to reduce the dosage, thereby reducing the cost and lightening the pollution to the environment, having good safety and meeting the requirements of decrement, synergy and green agricultural development.
The composition of the present invention has an excellent herbicidal effect on annual or perennial weeds in paddy fields.

Example 1: toxicity determination of oxadiargyl and carfentrazone-ethyl on cyperus heterophyllus
Test subjects: special-shaped sedge seed
The test method comprises the following steps: the test was conducted with soil without treatment with the drug. Adding test soil into a flowerpot, adding water until the soil is completely wet, and respectively and uniformly sowing the special-shaped cyperus rotundus seeds soaked for germination in the flowerpot. Adopting a greenhouse potting method, carrying out soil spraying treatment after sowing for 24 hours, repeating the treatment for 4 times, and additionally arranging a blank control. Culturing in a greenhouse after treatment, periodically supplementing water in a bottom irrigation mode, and keeping the soil humidity of 100%. Weed response symptoms were recorded after treatment with regular observation. And 28d, calculating the fresh weight of each treated weed. The data were analyzed using the sps software to calculate the ED50 value, and the joint effect was evaluated according to the Sun cloud Peel method.
TABLE 1 Populyn and carfentrazone virulence determination of sedge heterotypii
The data recorded in table 1 show that the ratio of oxadiargyl to carfentrazone-ethyl is within the range of the set ratio, the control effect on the abnormal-shape sedge is good, the antagonism is not generated, particularly, the synergistic effect is obvious when the ratio of oxadiargyl to carfentrazone-ethyl is 5: 1 and 10: 1, and the dosage of a single agent can be reduced.
