Description

  The present invention relates to a method for controlling horsetail, which comprises applying a composition containing an amino acid herbicide to horsetail.

  Amino acid herbicides, in particular N-phosphonomethylglycine (generic name: glyphosate) or salts thereof generally require the presence of a suitable surfactant to obtain high herbicidal performance. Surfactants can be provided in high concentration formulations or can be added by the end user to the diluted spray solution. For example, in a wide range of studies reported in Non-Patent Document 1 below, Wyrill and Burnside have found that the ability of glyphosate to enhance herbicidal activity varies widely among surfactants.

  However, an effective surfactant has not yet been found for grass species that are difficult to control (eg, horsetail, clover, communis, smelt). Therefore, in order to control these species, amino acid herbicides that are several times the normal dose are actually used. In particular, horsetail is required to be as fast as possible with vigorous fertility in the underground. And even if the above-ground part dies, since the roots are very deep and widely distributed, the above-ground part can be newly regenerated from the root nodes and continue vegetative propagation. Numerous tubers develop in the roots, and numerous vegetative stems are generated from the tubers. Therefore, it is required that the amino acid herbicide absorbed from the above-ground part is very excellent in migration to the root part. In addition, sugiina is considered to have a smaller amount of drug adhesion than other grass species due to the shape of the above-ground part, and a preparation excellent in adhesion is required.

Patent Document 1 discloses a method for improving glyphosate rain resistance using an acetylenic diol, but it does not disclose anything effective in controlling horsetail, which is a grass species that is difficult to control.

  The composition used in the present invention is mixed with a suitable liquid carrier or solid carrier, and further, if desired, a penetrating agent, a spreading agent, a thickening agent, an antifreezing agent, a binder, an anti-caking agent, a disintegrating agent. , Antifoaming agent, antiseptic, coloring agent, stabilizer and anti-degradation agent, etc., to add emulsion, emulsifiable concentrate, soluble concentrate, wettable powder, water dispersible It is manufactured as a formulation such as granule, aqueous suspension concentrate, suspoemulsion, dustable powder, granule and gel. In addition, from the viewpoint of labor saving and safety improvement, the composition used in the present invention includes the above preparation encapsulated in a water-soluble package such as a water-soluble capsule and a bag of a water-soluble film.

  Examples of the solid carrier include natural minerals such as quartz, kaolinite, pyrophyllite, sericite, talc, bentonite, acid clay, attapulgite, zeolite, and diatomaceous earth, calcium carbonate, ammonium sulfate, sodium sulfate, and potassium chloride. Inorganic salts, synthetic silica and synthetic silicates can be mentioned.

  Examples of the liquid carrier include alcohols such as ethylene glycol, propylene glycol and isopropanol, aromatic hydrocarbons such as xylene, alkylbenzene and alkylnaphthalene, ethers such as butyl cellosolve, ketones such as cyclohexanone, and γ-butyrolactone. Examples include esters, acid amides such as N-methylpyrrolidone and N-octylpyrrolidone, vegetable oils such as soybean oil, rapeseed oil, cottonseed oil and castor oil, and water, with water being preferred.

  These solid and liquid carriers may be used alone or in combination of two or more.

  As the above thickener, organic, inorganic natural products, synthetic products and semi-synthetic products can be used. For example, heteropolysaccharides such as xanthan gum (xanthan gum), welan gum and rhamzan gum, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic Synthetic water-soluble polymer compounds such as acid, sodium polyacrylate and polyacrylamide, cellulose derivatives such as methylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxyethylcellulose and hydroxypropylcellulose, montmorillonite, saponite, hectorite, bentonite, pendelite, nontrole Mention may be made of smectite clay minerals such as knight, saucolite, steppenside, laponite and synthetic smectite. These thickeners may be used singly or in combination, and the ratio in the case of mixing can be freely selected. These thickeners may be added as they are, or those previously dispersed in water may be added. Moreover, the addition amount at the time of adding to the composition used by this invention can also be selected freely.

  Examples of the antifoaming agent include silicone emulsion antifoaming agents.

  As the stabilizer, an antioxidant is preferable, for example, ethylenediaminetetraacetate calcium disodium, ethylenediaminetetraacetate disodium, erythorbic acid, sodium erythorbate, isopropyl citrate, dibutylhydroxytoluene, butylhydroxyanisole, gallic acid.

  The composition used in the present invention is preferably a liquid, and can be produced by mixing an amino acid herbicide, an acetylenic surfactant, other adjuvants and the like with water or the like and uniformly dissolving the mixture.

  In use, the composition is diluted 1 to 10,000 times with water or sprayed undiluted.

[Test Example 1] Herbicidal effect test by foliar treatment Put sterilized flooded soil in a 5 inch plastic pot, embed tubers or seeds, cover about 1.5 cm, and then in a greenhouse at 25 ° C Growing plants. After growing for 30 days, the composition shown in Table 1 was diluted with predetermined spray water and uniformly treated with a small spray on the foliage. The amount of chemicals used and the amount of sprayed water are shown in Table 2.

  Twenty days after the drug treatment, the herbicidal effect on various plants was investigated according to the criteria of 0 = no effect to 100 = complete killing. The results are shown in Tables 2 and 3.

  The present invention is effective for controlling horsetail, and is excellent in progress of herbicidal effect and final control effect.
