[Detailed description of the invention] Improved formulations of herbicides and their use background This application is a co-pending application filed on June 14, 1988 vss NO 7/206.40 This is a partial continuation application of No. 5.

The present invention relates to herbicides, particularly acifluorfen, agriculturally acceptable salts thereof, Fluorfen, lactofen, imadecic acid and agriculturally acceptable salts thereof , N-phosphonomethylglycine and agriculturally acceptable salts thereof, mixtures thereof Relating to methods and compositions for enhancing the efficacy of herbicides selected from the group consisting of Ru.

The present invention provides a ready-to-use composition containing an enhanced delivery system for herbicides. related.

Herbicides can be applied to plants in a variety of ways, including different formulations. Of these various methods , the use of liquid and dry compositions is highly desirable. desired special prescription and its consequences; The effectiveness of fruit enhancement depends on the weed species treated, environmental conditions, geographic region, and location at the time of treatment. Much depends on the climate of the region.

In many parts of the world, areas with high rainfall or prefectures and rainfall after herbicide application are Regular application of herbicide compositions with rainwater adhesion properties (adhesion to leaves) at predictable times It is highly desirable to do so. Additionally, some regions have thick cuticles, Therefore, herbicide compositions (typically one species of It is particularly desirable to apply herbicidal compositions).

The use of the compositions of the invention is suitable for rhizomatous Seiban sorghum, pincer perennials, and seedling seedlings. Ivan sorghum, golden millet and pincers - on the annual plant downy sycamore In contrast, application of herbicides according to the invention particularly resulted in an increase in herbicide efficacy.

The exemplary chemical compositions of the invention used in the tests were formulated as tank mixes on the day of application. . The formulation is an agriculturally acceptable salt of N-phosphonomethylglycine, i.e. lopylamine salts, surfactants, humectants, organosilicon surfactant copolymers and Contains inert auxiliaries such as water.

The application rate based on N-phosphonomethylglycine is approximately 1/8 to 1 knee car. The range was approximately 3 pounds of glyphosate acid equivalents. The ingredient ratio used in the formulation is The phosate to surfactant ratio is approximately 1:0.125 to 1:1, surfactant to silico The ratio of silicone surfactant to humectant is approximately 1:0.45 to 1:20, and the ratio of silicone surfactant to humectant is approximately 1. 1 to about 1:200. Rainfall processing simulates approximately 1/4 inch of rain within approximately 15 minutes. I of the composition using a rainwater tower with a scale on the amount! It was applied 1 hour after J fog.

After the rain application, the treated seed was placed on a cart and transferred to the greenhouse. After the plants are sufficiently dry , the pots were returned to the trays in the greenhouse and arranged in a randomized complete block trial design. Ta. Each treatment was repeated three times. Control plants and appropriate standard treatments were It was used in experiments. Duplicate trials of similarly treated plants receiving the same treatments as rainfall treated plants. The experimental set was provided for comparison under no-rainfall conditions.

Observation of the treatment effect is carried out within 7 to 10 days to see if the early burning has faded and the treatment is repeated. Long-term effects were performed within 21-28 days after treatment. Weed rating scale from 0 to 100% It was used to evaluate the degree of pest control. 0% has no appreciable effect. 100% is completely sloppy kill the grass. Degree of burn b1 blanching phenomenon, reduction of only the cheekbones and back and included in the test Other possible effects of the treatments on the plant species involved were taken into account in developing the ratings.

Although the invention is described with respect to specific modifications, the details thereof are not to be construed as limitations. The following examples illustrate the compositions and methods of use of the present invention.
