IMPROVED PROCESS FOR THE PREPARATION OF PYRETHROIDS

The present disclosure concerns a process for preparing a pyrethroid, said process comprising the steps of: a) reacting an acid chloride with an alcohol in a suitable organic solvent and in the presence of a nitrogen acid acceptor in a temperature range from 0°C to 40°C; and b) washing with water and/or an aqueous basic solution, wherein a suitable amount of a polyamine (W) H2N-(CH2)b-Ae-[(CH2)c-A-]p-(CH2)d-NH2, where A is -NH- or -O-, b and d are independently an integer in the range of 1 -5, c is an integer in the range of 2-5, e is an integer from 0 to 1, p is an integer in the range of 0-5, is added in step a) or b) or after step a) and before step b).

Insect pest control method

PCT No. PCT/JP95/01568 Sec. 371 Date Feb. 10, 1997 Sec. 102(e) Date Feb. 10, 1997 PCT Filed Aug. 7, 1995 PCT Pub. No. WO96/04786 PCT Pub. Date Feb. 22, 1996Provided is a technique comprising blowing air onto a carrier having supported thereon a preparation containing a highly safe pesticidal component to vaporize and diffuse the component from the preparation under non-heating conditions thereby to control flying insect pests. An insect pest control method characterized by preparing a preparation-retaining material by supporting on a carrier a preparation containing a pesticidal component which is hard to vaporize at normal temperature, preferably at least one pesticidal component selected from compounds which are hard to vaporize at normal temperature and have a vapor pressure of lower than 1x10-3 mmHg and a boiling point of not lower than 120 DEG C./1 mmHg, setting the resulting preparation-retaining material, and contacting the preparation with an air current raised by an air blowing means to release the component into the air under non-heating conditions, an apparatus suitable therefor, and a carrier to be used in the preparation-retaining material set in the apparatus characterized by not blocking the air current toward the vent hole of the apparatus are provided.

Pesticide compositions and method

Toxicant, especially pesticide compositions, having lowered dermal toxicity are provided. The compositions include a lipophilic-pesticide, a nonionic surfactant and a dry inert diluent carrier. Methods for reducing the dermal toxicity of lipophilic toxicants, especially pesticides are provided, as well as methods for controlling insect pests using the disclosed compositions.
