A granular pesticidal composition in which a powdery pesticide is aggregated and coated with a thermosetting resin is capable of enabling a pesticidal active ingredient to be controlled-released. Further, the controlled-release pesticidal granule can be produced by mixing a powdery pesticide with a first liquid component serving as a raw material for a thermosetting resin, a process of adding a second liquid component serving as a raw material for a thermosetting resin, and then making the first liquid component react with the second liquid component to produce a thermosetting resin.

Method for producing a pesticidal composition

Disclosed is a powdery pesticidal composition which comprises a mixture of a coated pesticide comprising a powdery pesticide coated with a thermosetting resin and having a volume median diameter of 10 to 150 &#x3bc;m and a calcium carbonate micropowder having a bulk density of 0.6 g/ml or less, wherein the weight-based ratio of the coated pesticide to the calcium carbonate micropowder is 100:1 to 100:30. The powdery pesticidal composition has good fluidability.

Powdery pesticidal composition

A coated seed obtained by coating a seed with a coating material containing an inorganic mineral powder and a thermosetting resin powder having an average particle diameter of 10 to 200 &#x3bc;m, wherein the thermosetting resin powder is a thermosetting resin powder obtained by aggregating a powdery pesticide with a thermosetting resin has an excellent quality.

Coated seed

Insecticidal wettable powders containing an insecticide which is liquid at room temperature and a calcined synthetic hydrated silicon dioxide, which can retain its insecticidal effect for a long time without separating oil drops when used by diluting with water.

Insecticidal wettable powder

A fungicidal composition containing a fungicidally effective amount of tolchlofos-methyl [O,O-dimethyl O-(2,6-dichloro-4-methylphenyl) phosphorothioate] as an active ingredient, attapulgite clay as a carrier and polypropylene glycol as a stabilizer, its formulation and its use as a fungicide.

Fungicidal composition

A pesticidal aqueous suspension having an excellent dispersion stability, which comprises, as a pesticidally active ingredient, an N-methyl- or N-phenylcarbamate which is solid and has a solubility in water of about 10 to 10,000 ppm at room temperature, suspended in water in a finely dispersed state with a surfactant having a hydrophilelipophile balance (HLB) less than 5 and polyvinyl alcohol having a degree of hydrolysis of about 70 to 90 mol % and a degree of polymerization of about 300 to 2,600 as dispersing agents in the presence of ethylene glycol and liquid paraffin as dispersion stabilizers.
