CONTROLLER FOR TREE MATERIAL DECAY DISEASE DAMAGE

摘要

PROBLEM TO BE SOLVED: To obtain a controller for a decay disease damage caused by infection with a basidiomycete such as Phaeolus schweintzii, a fungus of the genus Russula or Armillariella mellea. ;SOLUTION: This controller for a tree material decay disease damage contains a spore of a fungus belonging to the genus Trichoderma. The controller is produced by suspending an agrochemical containing ≥50,000,000 live spores of Trichoderma in 1g on the market in water of 500-5,000 times as much as the agrochemical. The controller is sprayed by boring a hole into which a nozzle part of a spraying machine is introduced when an interior of root and trunk of terrestrial part is decayed into a hollow part. The controller is sprayed or applied when the opening part is exposed.;COPYRIGHT: (C)1997,JPO
