The present invention provides diazinon [0-(2-isopropyl-4-methyl-pyrimidinyl-6-)0,0
-Diethylthiophosphate] Concerning the stabilization of powders as active ingredients. Diazinon is an insecticide with relatively low toxicity and low accumulation, and is highly effective against various pests of rice, rapeseed, and fruit trees. Stabilization in mixed powders has important significance. Regarding prevention of decomposition of diazinon, a method of adding an epoxy group-containing compound (Japanese Patent Publication No. 43-17757)
and a method of adding diethanolamine or triethanolamine in combination with a surfactant (Japanese Patent Application Laid-Open No. 1989-1999)
-157831) is known. In the process of investigating more practical stabilizing means for powders, the present inventors discovered that while powders of general organic phosphorus agents are stable under dry conditions, unexpectedly, diazinon powders are stable under humid conditions. It was found to be remarkably stable. Based on this knowledge, various methods for retaining moisture in diazinon powder were investigated and the present invention was developed. In the present invention, a hydrate of an inorganic salt is blended into a powder containing diazinon, and the hydration content in the powder is adjusted to 0.3 to 5.0.
This is a method for stabilizing diazinon powder by maintaining it at %. The hydrate of the inorganic salt to be blended may be one that does not have an adverse effect on diazinon and other agricultural chemical active ingredients that may be blended at the same time, and does not pose a risk of environmental pollution. For example, Na 2 SO 4・10 or 7H 2 O, Na 2 CO 3・10 or 7H 2 O, Na 2 HPO 4・12H 2 O, Na 3 HPO 4・12H 2 O, Na 2 B 4 O 7・10H 2 O, K 2 CO 3・2H 2 O K 2 SO 4・Al 2 (SO 4 ) 3・24H 2 O CaCl 2・6 or 4H 2 O, MgCl 2・6 or 4H 2 O, MgHPO 4・7H 2 O , MgCO 3・5H 2 O, Al 2 (SO 4 ) 3 (NH 4 ) 2 SO 4・24H 2 O, FeSO 4・7H 2 O, FeCl 2・6H 2 O, MnSO 4・7H 2 O, ZnSO 4・7H 2 O, alkali metals, alkaline earth metals, or cations such as Al, Fe, Mn, Zn, and sulfuric acid,
Mention may be made of water-soluble salts or complex salts in combination with anions such as carbonic acid, phosphoric acid, fermentation or hydrochloric acid. Particularly preferred is CaCl 2.4 or 6H 2 O.
MgCl 2 O.4 or 6H 2 O. Hydrates of these inorganic salts can be incorporated into powders as they are, but it is also possible to use anhydrous or intermediate hydrates and add the required amount of water, or to use water from other adjuvants in the formulation. It can also be made into a suitable hydrate. In the present invention, the amount of the inorganic salt hydrate to be incorporated into the powder is selected so that the water content in the powder is in the range of 0.3 to 5.0%. Preferably it is in the range of 0.3 to 2.0%. When the moisture content exceeds 5%, the physical properties of the powder,
In particular, fluidity deteriorates, and to improve it, it is necessary to add excessive amounts of white carbon, etc.
Unfavorable in various ways. The method of compounding is to mix a powdered or granular inorganic salt hydrate with a main ingredient, a mineral carrier, and other auxiliary agents, and then to form a powder, or to mix it into a pre-prepared powder. Add the powdered inorganic salt hydrate and mix uniformly. The powder containing the inorganic salt hydrate of the present invention does not need to be packaged to prevent moisture permeation; rather, a normal kraft bag can sufficiently maintain its stabilizing effect. Examples of the present invention will be given below. Example 1 33.3 parts of calcium carbonate, diazinon raw material (93
%) 1.3 parts, MPMC Premix [mixed powder product of 76.5 parts of MPMC bulk (98%) and 23.5 parts of white carbon] 2.2 parts, white carbon 2.0 parts, PAP
(mono and diisopropyl phosphate mixture) 0.2
and 1.0 part of calcium chloride (hexahydrate) were mixed and milled using a hammer mill. 60.0 parts of clay (Fuhi) was added to this mixture in a ribbon type mixer and thoroughly mixed to obtain a powder with a moisture content of 0.71%. Example 2 MTMC premix [MTMC bulk (98%)
Mixed powder frame product of 76.5 parts and 23.5 parts of white carbon]
2.2 parts of white carbon, 2.0 parts of white carbon, 1.3 parts of diazinon raw material (93%), 0.2 parts of PAP and 32.3 parts of calcium carbonate were mixed and powdered in a hammer mill. Place this in a ribbon-type mixer, add 2.0 parts of sodium carbonate (decahydrate: powdered product) and clay (fuhi).
60.0 parts were added and thoroughly mixed to obtain a powder with a moisture content of 1.38%. Example 3 Calcium carbonate 33.2 parts, white carbon 2.5 parts
part, 1.3 parts of diazinon raw material (93%), 1.0 part of Driles A [drift inhibitor, manufactured by Sankyo Co., Ltd.], and regular water.
1.0 part was mixed and milled using a hammer mill. Place this in a ribbon mixer, add 1.0 part of calcium chloride (anhydrous, powder) and cut clay (particle size
60.0 parts (cut into 10-40 μm) were added and thoroughly mixed to obtain a powder with a moisture content of 0.9%. Example 4 MPMC Premix (same product as Example 1) 2.2
part, white carbon 2.5 parts, magnesium chloride (hexahydrate) 1.5 parts, diazinon raw material (93%)
1.3 parts, Drilleth A 1.0 parts and calcium carbonate
31.5 parts were mixed and ground in a hammer mill. This material was placed in a ribbon mixer, and 60.3 parts of cut clay was added and thoroughly mixed to obtain a powder with a moisture content of 0.92%. Example 5 MPMC Premix (same product as Example 2) 2.2
part, 2.5 parts of white carbon, 1.0 parts of Drilless A,
1.3 parts of diazinon raw material (93%), 1.0 part of ferrous sulfate (heptahydrate), and 32.0 parts of clay were mixed and ground in a hammer mill. This material was placed in a ribbon mixer, 60.0 parts of cut clay was added thereto, and thoroughly mixed to obtain a powder with a water content of 0.4%. Next, test examples of the present invention will be shown. [Test method] The prepared powder was placed in a glass bottle with a stopper, sealed and stored in a constant water bath at 50°C for 4 weeks, and then the diazinon content of each was quantified and the residual rate relative to the initial content was determined. The water content in the formulation was measured using the Karl Fischer method (digital automatic moisture measuring device KF-01 manufactured by Mitsubishi Kasei). [Test Results] Tables 1 to 4 show the results of time-lapse tests conducted on powders prepared according to the methods of Examples 1 to 5 described above, and the residual ratio of diazinon relative to water content. Incidentally, the increase/decrease in the amount of inorganic salt hydrate, etc. blended into the powder was adjusted by increasing/decreasing the amount of clay or cut clay.
