METHOD FOR BIOLOGICAL CONTROL OF GALBA MOLLUSKS IN WATER RESERVOIRS THAT ARE TEMPORARY BY HYDROLOGICAL MODE Russian patent published in 2010 - IPC A01N65/00 

FIELD: agriculture.

SUBSTANCE: hygro- and mesophilous plants having molluscicide activity to amphibiont mollusks - intermediate hosts of F.hepatica are introduced with account of ecological zones of moisture: 1^st zone - zone of shallow water to 50 cm on water surface to coast brinks; 2ns zone - zone of raw areas of 50 cm to coast brink or to 50 cm from coast brink; 3^rd zone - zone of coasts of 50-100 cm from coast brink and area of water mirror. The following plants are used for introduction, separated into 3 groups: 1^st group - sedge cane Acorns calamus L. and cowberry Comarum palustre L.; 2^nd group - snakeweed Polygonum bistorta L., water avens Geum rivale L., killweed Lythrum salicaria L. and tormentil cinquefoil Potentilla erecta (L.) Rauesch; 3^rd group - common avens Geum urbanum L. and greater burnet Sanguisorba officinalis L.

EFFECT: reduced count of Galba molluscs in water reservoirs that are temporary by hydrological modes and prevention of their repeated occupation with these molluscs into Galba biotopes temporary by hydrological mode.
