CONTROL OF INSECTS.
EPSOM SALTS SPRAY Discoveries of new ways to destroy insects continue to be made, some of them being quite surprising. Thus science reports the discovery that epsom salts has been found a very efficient poison to certain insects, while with others it is useless.
This very inexpensive material has been found effective as a spray against the bean bettie. It is also toxic to the wheat wireworm. It greatest use, however, will be as a grasshopper poison. A moist mixture of bran, molasses and epsom salts used experimentally on grasshoppers proved an inexpensive and efficient poison bait. For some years past a solution of 2oz epsom salts to 1 gallon of water has been used in Hawke’s Bay and other districts where the white butterfly has established, as an effective spray to destroy the grubs on cabbage and cauliflower.
