Description
Technical field:
the invention belongs to the field of pesticide dosage forms, and in particular relates to a penoxsulam and haloxyfop-methyl dispersible oil suspension agent, and a preparation method and application thereof
Technical Field
The dispersible oil suspending agent is a dosage form in pesticide preparations, and is a high-dispersion stable suspension system taking a non-water system (oil-based) as a dispersion medium. The oil generally comprises vegetable oil and derivatives thereof or mineral oil, and the like, replaces the traditional organic solvent, has the characteristics of low toxicity, easy degradation, environmental friendliness and the like, and has good adhesiveness and spreadability, is easy to adhere to a waxy layer on the surface of a plant when being used as a dilution carrier, and can play a role in synergism on some pesticides with strong lipophilicity (such as nicosulfuron herbicide).
Penoxsulam (Penoxsulam), cas no: 219714-96-2 is a post-emergence herbicide developed by the United states Dow company and has the mechanism of inhibiting the acetolactate synthase (ALS) of weeds to kill weeds, is effective against barnyard grass (including barnyard grass resistant to propanil, quinclorac and ACCase inhibitor herbicides), annual cyperaceae weeds, and is effective against a wide variety of broadleaf weeds. The pesticide has long period, can be used from one leaf of rice to one heart of rice to maturity, has the lasting period of penoxsulam up to 30-60 days, and can basically control the harm of weeds in all seasons by once pesticide application.
Penoxsulam (pyroxasulfone), chemical name: 3- (5- (difluoromethoxy) -1-methyl-3-trifluoromethylpyrazole-4-methylsulfonyl) -4,5-2H-5, 5-dimethyl-1, 2-oxazole has the formula: c (C) 12 H 14 F 5 N 3 O 4 S, relative molecular mass: 391.31.
the haloxyfop-methyl belongs to a novel pyrazole selective pre-emergent sealing herbicide, and is applied to control main gramineous weeds and partial broadleaf weeds in dry-land crop fields before emergence of seedlings. Compared with the prior art, the pre-emergent blocking herbicide has a plurality of advantages: the application time range is wide, the application can be carried out from the pre-planting to the post-emergence, and the application is compatible with most common herbicides. The mechanism of action is to exert the efficacy by inhibiting the ultra-long chain fatty acid extension synthetase. The haloxyfop-butyl converts stearic acid into arachidic acid, arachidic acid into behenic acid, behenic acid into lignoceric acid, lignoceric acid into cerotic acid, cerotic acid into montanic acid in the biosynthesis pathway of ultra-long chain fatty acid synthetase in plants, and finally inhibits the synthesis of myristic acid. The product has wide application range, and can be used for corn, peanut, sunflower, soybean, cotton and other crops; is safe to the environment, and is safe to the current crop and the next crop.
The dispersible oil suspending agent which is prepared by combining the halofop-butyl and the penoxsulam is not registered in the market at present, the dispersible oil suspending agent is creatively prepared by combining the halofop-butyl and the penoxsulam, the weeding spectrum can be improved, the defects of more harmful solvents of emulsifiable concentrates, large environmental pollution, poor weeding effect of the suspending agent and the like are avoided, and the suspending agent has higher economic value.
In the process of using penoxsulam and haloxyfop-R-methyl herbicide, if the soil moisture content is poor, the herbicide can produce phytotoxicity to rice in case of poor drainage or extreme weather such as dry weather, less rainfall, low temperature after application, and the like, and is shown to inhibit the growth of rice, rice She Fahuang has an influence on the yield of rice. The inventive addition of the safener 2-methoxy-N- [ [4- [ [ (methylamino) carbonyl ] amino ] phenyl ] sulfonyl ] benzamide can greatly improve the safety of penoxsulam and paraquat sulfone to rice, and has higher economic value.

2. Main performance index test of penoxsulam-haloxyfop-methyl dispersible oil suspension
Testing main performance indexes of penoxsulam-metazophos dispersible oil suspending agents of the above examples 1-3 and comparative examples 1-15, and measuring the suspending rate by referring to a GB/T14825 pesticide suspending rate measuring method; the method for measuring the cold and hot storage stability refers to a method for measuring the low-temperature stability of a GB/T19136-2003 pesticide and a method for measuring the hot storage stability of the GB/T19136-2003 pesticide respectively, and specific data are shown in Table 1.
The detection method of the emulsifying dispersibility comprises the following steps: slowly adding 1mL of emulsifiable concentrate into a beaker filled with hard water at a position 2cm away from the water surface by using a syringe, and observing the emulsifying and dispersing state;
determination criteria for water-in emulsification and dispersion state:
first-order: can be rapidly and automatically dispersed evenly, and slightly stirred to form blue or pale transparent emulsion;
and (2) second-stage: can automatically disperse in white cloud and slightly stir to form blue semitransparent emulsion;
three stages: filiform dispersion, and after stirring, the emulsion is blue opaque;
four stages: the white microspheres sink and are white opaque emulsion after stirring;
five stages: the oil beads sink, can be emulsified during stirring, and can be layered after stopping stirring.
TABLE 1
As can be seen from Table 1, the invention selects a reasonable component system, has good emulsification effect under the synergistic effect of the components, and all performance indexes are qualified.
3. Field efficacy and safety test
Test agent: examples 1-3 and comparative examples 1-15 penoxsulam-haloxyfop-methyl dispersible oil suspensions;
control object: barnyard grass. Safety: rice plant
The test method comprises the following steps: the test was run in the field and each group was treated 3 times in duplicate with a treatment area of about 60m 2 And a blank control area is arranged, the application period is 7 days after the rice is transplanted, the growth vigor is good, the plants are strong, and other diseases and insect pests are avoided. The administration method comprises the following steps: the toxic soil method is adopted for drug application, so that uniform spreading is realized. The growth of rice was observed 7d after the application, the death of weeds was observed 15d after the application, and the herbicidal activity of each agent was compared. The results are shown in Table 2.
TABLE 2
As is clear from Table 2, examples 1 to 3 of the present invention (all with safeners added) were safe to rice under the conditions equivalent to the test, and comparative example 1 showed dwarfing and yellowing of leaves due to the absence of safeners, and comparative example 14 showed dwarfing and yellowing of leaves due to the addition of different safeners. The weeding effects of the invention for the barnyard grass in the examples 1-3 are better than those of the invention in the comparative examples 2-13 and 15, and the weeding effect is better in popularization value.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
