Actual registrations for post harvest disinfestations and perspectives in France

Abstract

During the last few years, many pesticides were banned. For SPP, in France, this situation is particularly critical since they were key compounds. For grain, DDVP was used to meet the requirement of zero insect when the grain was sold, for mills, methyl bromide and DDVP were the base of the disinfestation.
France is reluctant to employ gases like phosphine for grain, but as long as contact insecticides will be permitted, they will be used. Ethyl formate, applied as a liquid, but acting as a gas, could be an interesting compromise. Research shows good results but sorption, and then distribution in the grain, is the main problem to overcome. Mills are in a bad position since DDVP has no alternative and, as a result, curative disinfestation is not an option, heat or fumigation.
