Embodiment 1

[0020] Biological Assay Example 1: Determination of the joint effect of the combination of fenoxaprop-ethyl and bentazone on weeds.

[0021] Test material: Chickweed[ Stellaria media (L.) Cyrillus] (seed collection in field preservation). barnyard grass [ Echinochloa crusgalli (L.) Beaw Setaria] (field collection of seeds for preservation).

[0022] Test equipment: controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0023] Test method: first weigh a certain mass of 95% fenoxaprop-ethyl technical substance and 96% bentazone technical substance, add acetone to fully dissolve it, dilute it with 0.1% Tween 80 aqueous solution, and prepare a single-dose mother solution respectively. Set a series of proportions for the purpose of mixing, and set 5 to 7 concentration gradients for each proportion. Select representative sensitive weed seeds according to the single-dose herbicidal spectrum for fut...

Embodiment 2

[0037] Formulation Example 2: 22.5% fenoxaprop-ethyl-benzazone water-dispersible granules.

[0038] Fenoxaprop-P-P 2.5%, Benazone 20%, Sodium Lauryl Sulfate 10%, Polycarboxylate 5%, Sodium Chloride 6%, Polyethylene Glycol 4%, Kaolin Clay to 100%.

[0039] Dry pulverize, granulate, dry and sieve the above formula according to the proportion to prepare 22.5% fenoxaprop-ethyl-benzazone water-dispersible granules.

[0040] Formulation Example 3: 15% fenoxaprop-ethyl-benzazone aqueous emulsion.

[0041] Fenoxaprop-ethyl 3%, bentazone 12%, N-methylpyrrolidone 8%, sodium dodecylbenzene sulfonate 8%, polyvinyl alcohol 4%, emulsifier 500# 7%, silicone disinfectant Foaming agent 0.9%, deionized water to make up to 100%.

[0042] Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix the water-soluble components in the above formula with deionized water to obtain a water phase; under high-speed stirring, mix the oil phase and water phase ...

Abstract

The invention discloses a herbicidal composition containing fenoxaprop-P-ethyl and bentazone, which has the effective components of fenoxaprop-P-ethyl and bentazone with weight ratio of 20:1-1:30, preferably the weight ratio of fenoxaprop-P-ethyl to bentazone is 10:1-1:20. The combination of fenoxaprop-P-ethyl and bentazone has obvious synergic effect; the amount of effective components of the combined composition is obviously reduced over either component used alone. The herbicidal composition of the present invention is suitable for preventing and weeding annual grassy weeds in paddy fields.

Description

technical field [0001] The invention relates to a herbicidal composition, which uses fenoxaprop-ethyl and bentazone as active ingredients and is used for controlling annual weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and young and old weeds occur alternately, so when the herbicide species are used alone , will show a certain aspect of defects and limitations. [0003] Fenoxaprop-P-ethyl belongs to aryloxyphenoxypropionic acid herbicides and is a fatty acid synthesis inhibitor. After being absorbed by the leaves of plants, it is transported to the leaf base, stems, and roots, and inhib...
