The present invention improves the disintegration and spreadability of agrochemical granules for water surface application, which are produced by granulating a pesticide active ingredient and a clay carrier. BACKGROUND ART Conventionally, pesticide granules have been widely applied to rice fields for the purpose of weeding, insecticidal, and sterilizing rice fields. Such pesticide granules are generally produced by mixing the active ingredient into a clay carrier such as bentonite and granulating it, or by adsorbing or coating the active ingredient on the granulated base granules, and when applied in water. It is necessary to collapse and expand quickly. Incidentally, depending on the type and blending ratio of the clay carrier, or when the water hardness is high, the disintegration and spreadability of the granules in water may be poor.
Therefore, improvements in formulation are desired. The present invention is a pesticide granule containing a chelate compound of a polyaminocarboxylic acid or a salt thereof and a condensed phosphate and having good disintegration and spreadability in water. Examples of chelate compounds of polyaminocarboxylic acids or salts thereof include the following compounds. Ethylenediaminetetraacetic acid (EDTA) (HOCOCH 2 ) 2 N−CH 2 CH 2 −N
( CH2COOH ) 2diethylenetriaminepentaacetic acid (DTPA) Triethylenetetraaminehexaacetic acid (TTHA) Nitrilotriacetic acid (NTA) N(CH 2 COOH) 3 N-(2-hydroxyethyl)ethylenediaminetriacetic acid (HEDTA) Alkali metal salts, alkaline earth metal salts, and amine salts of these polyaminocarboxylic acids are also effective. Examples of condensed phosphates include the following compounds. Sodium tripolyphosphate Na 5 P 3 O 10 Sodium tetrapolyphosphate Na 6 P 4 O 13 Sodium ultra polyphosphate Na 2 P 4 O 11 The blending ratio of the above two components is polyaminocarboxylic acid
Condensed phosphate is used at a ratio of 80-40% to 20-60%, and the amount added is practically 1-40% to the clay carrier.
3% is used. Although it can be added as a powder, generally the polyaminocarboxylic acid is gradually added to water in which the condensed phosphate has been dissolved and stirred, and if it does not become transparent, the pH is adjusted to 6.5 to 6.5 with an acid or alkali.
Adjust to 8 to make a clear liquid. It is added at an appropriate stage of granulation. As a clay carrier, montmorillonite group minerals such as bentonite are generally used, but carriers such as calcium carbonate, talc, clay, kaolin, sericite, and diatomaceous earth can also be used.
These carriers are usually used in combination with bentonite.
In addition, lignin sulfonate, alkylbenzene sulfonate, polyvinyl alcohol, etc. are added and used for various purposes. Granules are manufactured in a conventional manner by mixing a carrier, a solid agricultural chemical substance, and a disintegrating extender, blending, granulating, drying,
The base granules are produced by sizing, or by mixing, admixing, granulating, drying, and sizing the carrier and disintegrating spreader, and
It is produced by adsorbing or coating a liquid agricultural chemical raw material onto these base particles. Test examples of the agricultural chemical granules of the present invention are shown below. Test Example Collapse Spreadability Test An aqueous solution of 22 parts of bentonite, 76 parts of calcium carbonate, 1 part of Amicol No. 1 (binder), and 1 part of disintegration spreader in various mixing ratios was mixed, granulated, and dried.
The grains were sized into mesh to obtain base grains (weighing approximately 1.0 mg/grain). Five of these base grains were placed in a shear dish containing 30 ml of water of a predetermined hardness, and the state of disintegration and expansion after 20 minutes was judged according to the following criteria. ◎ Completely collapses and expands. 〇Although most of them have collapsed, the expansion is slightly slower. Δ Partial collapse. × Does not collapse at all. The results are shown in Tables 1 to 5.
