[QUOTE="John B, post: 6647, member: 207"] I have had many hundreds of hives poisoned over the years by insecticides and surfactants. Having said that, spray poisoning is nowhere near as common as it used to be and most people behave responsible with their sprays these days. It is of course illegal to spray insecticides onto flowering plants that may be visited by bees and this includes flowering weeds in places like orchards. I have on occasions been asked to move bees because of spraying but I now have a fix policy of refusing to move hives as if spraying is done according to law it will not cause me any problems. My worst losses have been caused by gorse being sprayed. The herbicide is not toxic to the bees but unfortunately organo- silicate surfactants are deadly whether wet or dry and this is not listed on the label. Other surfactants are toxic to bees if they are sprayed directly with them but otherwise are relatively harmless. It is best practice to spray any plants either before or after they have flowered and that really removes any risks involved. Thank you for taking the time to ask this important question. If spraying absolutely has to happen then early morning and late evening of the best times to avoid too much contact with bees. Under no circumstances should sprays be applied over or immediately around beehives and this includes herbicide such as roundup as they can contaminate honey and cause problems with residues.
