Insecticide granules in mushroom culture

摘要

AbstractIn laboratory tests, chlorfenvinphos granules were distributed in various ways in mushroom casing (a peat/chalk mixture) to relate efficiency of mixing to effectiveness against larvae ofLycoriella auripila.Amounts giving complete control when thoroughly mixed, killed only 40 when “clumped”. Whenever untreated patches were provided, some larvae survived. Pulverising granules, however, improved control in thorough mixes.By using fluorescent granules it was found that insecticide incorporation in mushroom compost was very irregular after mixing in a spawning machine. At best, only half the compost was acceptably treated; that is, it received between a half and double the intended d
