The present invention provides a method for controlling a plant disease which comprises applying a compound represented by formula (I) [wherein Z represents a C1-C6 chain hydrocarbon group and the like, Rand Rare identical to or different from each other and represent a hydrogen atom or a fluorine atom, and R, R, R, Rand Rare identical to or different from each other and represent a C1-C6 chain hydrocarbon group and the like] to a plant or a soil, which has excellent control efficacies against plant diseases.

Phenylpyrazole compound and method for controlling plant disease

A valve removal method of a fluid pipeline structure, which removes an unnecessary portion of a valve device from a connection port portion side of a pipe without flow disruption in the fluid pipeline structure that detachably includes the valve device including a valve body, which is openable and closeable from a direction intersecting a flow path axis of a connection port portion, on the connection port portion side of the pipe connected to a fluid piping system includes a valve body fixing step of fixing the valve body at a closed valve position to the connection port portion side in a sealed manner; and a valve component removing step of removing other unnecessary valve components of the valve device in a state where the valve body which is fixed in a sealed manner is left on the connection port portion side.

Valve removal method of fluid pipeline structure, fluid pipeline structure, and valve device

A gate valve includes a valve body for insertion through a through-hole formed in the fluid pipe, and a movement mechanism for moving the valve body along the diameter direction, and the valve body includes a valve main body and a seal member that is capable of undergoing elastic deformation and is provided on a holding portion of the valve main body. A core member formed from a material harder than the seal member is embedded between an outer face of the seal member, which is on the lower side in the movement direction, and a leading end face on the protruding side of the holding portion.
