PURPOSE:To obtain a soil modifier highly improved in both chemical acting efficiency and the sustainability of chemical effectiveness, thus enabling expected effect to be attained adequately even at a very low level of application by holding a pesticidal component oh a specific material followed by being made into granules. CONSTITUTION:Residues such as various humus including bark compost, coffee grounds, strained lees left after squeezing fruit juice, or beer brewery sludge, residues left after squeezing vegetable fatty oil, cow manure, or other organic materials such as chaff are admixed or impregnated with a pesticidal component, followed by being made into granules of >=0.1mm in mean diameter, thus obtaining the objective soil modifier. This modifier is useful for preventing the disease turf and insect damages of various plants including golf course and for weeding useful vegetation areas. This modifier does not migrate into the soil when applied, readily falling even if attached to the upper parts of plant leaves and stems; as a result, virtually all the amount of such applied modifier forms a granular layer on the soil; therefore, the frequency of its application can be reduced, and thus it is advantageous. |
