Abstract

<P>PROBLEM TO BE SOLVED: To obtain an agrochemical composition for controlling horsetail or clover, excellent in the development of a herbicide effect and a final controlling effect. <P>SOLUTION: This agrochemical composition for controlling the horsetail or clover contains an amino acid-based herbicide, a fungicidal agent, and as necessary, a surfactant and/or a chelating agent. The method for controlling the horsetail or clover is to use the composition containing the amino acid-based herbicide and fungicide for the horsetail or clover. The method for reinforcing the controlling effect of the amino acid-based herbicide on the horsetail or clover is to combine the amino acid-based herbicide with the fungicide. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention provides an agrochemical composition containing an amino acid herbicide that can be easily sprayed and has an excellent control effect on horsetail or clover, and a horsetail or clover characterized by applying the composition to horsetail or clover. It relates to a method for controlling.

  Amino acid herbicides, particularly N-phosphonomethylglycine (generic name: glyphosate) or salts thereof generally require the presence of a suitable surfactant to obtain the best 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 found that their ability to enhance the herbicide efficacy of glyphosate 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. As for clovers, the above-ground part tends to remain, and even if the above-ground part once dies, new leaves are likely to be regenerated later, making it difficult to control.

[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 uniformly treated with a small spray on the foliage.

35 or 70 days after 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 Table 2.
