A predetermined amount of water was added to the mixture and kneaded, followed by extrusion granulation using a screen having a pore diameter of 5 mm.
  • the obtained granulated product is put in a polyvinyl chloride bag and shaken to adjust the granulated product until it becomes a rounded substantially cylindrical product having an aspect ratio of 1: 1 to 1: 3, and is heated to 60 ° C. And then left to dry for 1 hour, followed by classification using a mesh with an opening of 4 mm to obtain a granular agricultural chemical composition having a minor axis of 5 mm.
  • Test Example 1 Put 50 granular agricultural chemical compositions of Production Example 1 in a 50 mL screw tube, then place 50 granular agricultural chemical compositions of Reference Production Example 1 in the same screw tube, and invert the screw tube 30 times at a speed of 30 rpm. To prepare a mixed granular agricultural chemical composition. Further, a mixed granular pesticide composition was prepared in the same manner for the granular pesticide composition of Production Example 2-5 instead of the granular pesticide composition of Production Example 1. The mixed granular pesticide composition was observed, and the difficulty of the action of visually recognizing that each grain was uniformly mixed was evaluated. Table 1 shows a correspondence table between the color difference ⁇ E * of each granular agrochemical composition with respect to the granular agrochemical composition of Reference Production Example 1 and the observation evaluation results. ⁇ E * was determined by the following formula.
  • Test Example 2 Put 50 granular agricultural chemical compositions of Production Example 1 into a 50 mL screw tube, then place 50 granular agricultural chemical compositions of Reference Production Example 1 into the same screw tube, and invert the screw tube once at a speed of 30 rpm. A mixed granular pesticide composition was prepared. Further, a mixed granular pesticide composition was prepared in the same manner for the granular pesticide composition of Production Example 2-5 instead of the granular pesticide composition of Production Example 1. In any case, since the mixing is not sufficient, it is strongly estimated that the state is inhomogeneous. This mixed granular pesticidal composition was observed to investigate whether or not each grain could be visually discriminated. Table 2 shows the color difference ⁇ E * of each granular pesticide composition with respect to the granular pesticide composition of Reference Production Example 1, and a correspondence table of the survey results.
  • the cylinder containing the mixed granular pesticidal composition was made upright, and compressed air was blown from the lower bottom side to the upper bottom side of the cylinder for 30 seconds to flow the mixed granular pesticidal composition. Thereafter, the state of the mixed granular pesticide composition was visually observed. Furthermore, 10 granular agrochemical compositions were randomly taken from the upper layer of the cylinder, put into water, and the number of settled grains was measured. When the mixed granular pesticide composition is uniform, the theoretical number of settled grains is 5, and if classification is performed by the above-described classification by flow, the granular pesticide composition of each production example is used as a reference layer in the cylinder upper layer. Since the granular pesticidal composition of Example 2 is biased toward the lower layer, the actual number of settled grains decreases. The results are shown in Table 3.
  • Test Example 4 Put 33 granular agricultural chemical compositions of Production Example 5 in a 50 mL screw tube, then put 33 granular agricultural chemical compositions of Production Example 6 in the same screw tube, and then add 33 granular agricultural chemical compositions of Reference Production Example 1 to the same The mixture is put into a screw tube, and the screw tube is inverted once at a speed of 30 rpm to prepare a mixed granular agrochemical composition. Since this operation is not sufficiently mixed, it is strongly estimated that the state is uneven. When the mixed granular pesticide composition is observed, the color tone of the grains present in the upper layer, the middle layer, and the lower layer are different from each other, and it can be instantaneously determined visually that each granular pesticide composition is biased.
  • the mixed granular pesticide composition is further inverted 29 times.
  • this mixed granular pesticide composition is observed, three types of granular pesticide compositions having different colors are mixed and mixed together, exhibiting a macroscopically uniform mosaic appearance, and each grain is uniformly mixed. Can be determined visually.
  • Table 3 shows the color difference ⁇ E * of any two types of granular pesticide compositions among the three types of granular pesticide compositions constituting the mixed granular pesticide composition.
  • the mixed granular agricultural chemical composition of the present invention can be used for the production of agricultural chemicals with high uniformity.

Abstract

L'invention fournit une composition de pesticides granulaires mélangés permettant de juger facilement de son uniformité, et pouvant être mise en œuvre sans craintes par une personne pratiquant une opération d'épandage de pesticides, ou un mélange de pesticides mélangés ainsi qu'une composition de pesticides granulaires destinée à obtenir cette composition de pesticides granulaires mélangés et ce mélange de pesticides mélangés. Plus précisément, l'invention concerne une composition de pesticides granulaires mélangés dans un état tel qu'au moins deux sortes de composition de pesticides granulaires de compositions différentes sont mélangées, au moins lors de sa mise en œuvre. Cette composition de pesticides granulaires est caractéristique en ce que la différence de couleur (ΔＥ＊) représentée par un (système couleur Ｌ＊ａ＊ｂ＊) d'un espace colorimétrique ＣＩＥ１９７６ de deux sortes de composition de pesticides granulaires arbitraires comprenant ladite composition de pesticides granulaires mélangés, est supérieure ou égale à 4,5. L'invention concerne également une composition de pesticides granulaires comprenant un colorant destinée à configurer cette composition de pesticides granulaires mélangés, et un procédé de fabrication de cette composition de pesticides granulaires mélangés.
