摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A granular composition for use in the agricultural and horticulture fields is prepared by mixing an active ingredient, such as an insecticide, fungicide or herbicide and a solvent or a binder with a carrier consisting of 0-30% of particles larger than 149 .mu. (100 mesh), 40-90% of particles between 149 .mu. (100 mesh) and 46 .mu. (300 mesh) and 10-30% of particles smaller than 46 .mu.. Finely divided particles of moisture-absorbing substances may be added when the carrier has been moderately granulated in the course of the production process. The composition is suited for spraying by helicopters or multi-nozzle hoses on dusters, for example.
