Tests Show Bees Are In No Danger From Weedkillers
The beekeeper is naturally concerned with the question of whether the use of hormone weedkillers will constitute a new threat to the beekeeping industry by causing a heavy mortality in field bees, says the Journal of Agriculture. The higher concentrations of hormone weedkillers now being used and the lack of detailed knowledge available regarding their possible toxity to honey bees led to tests being conducted at the Animal Research Laboratory at Wellaceville, states the Department of Agriculture. The tests disclosed that the use of 2, 4-D and M.C.P. acid preparations as hormone weedkillers constitutes no hazard to the beekeeping industry. Other tests made at Wallaceville however, disclosed that the plant poison sodium D.N.0.C., a non-hor-mone type weedkiller, is toxic to bees and precautions should be taken to avoid losses in bees if it is used on a large scale, and advice should be sought from the local Apiary Instructor of the Department of Agriculture.
