Grasshoppers damage more than crops
Products containing active ingredients such as carbaryl, acephate, befenthrin, cyfluthrin esfenvalerate, MALATHION, and permethrin will generally do a good job of eliminating the young grasshopper nymph.

Dealing with the mosquito menace
The smell which enters my lungs as I open my doors and windows to give the insecticide freer passage has been indicative of the use of MALATHION.

Wiping is best for indoor pesticides

POOR storage continues to be potentially a weak link for quality in the cereal supply chain.
The second driver, says Mr Cook, is the continuing loss of insecticide products available for use in grain stores. MALATHION (co-formulated with bifenthrin in Prostore) has recently failed to achieve Annex 1 listing, leaving pirimiphos-methyl (Actellic/ Fumite) and chlorpyrifos-methyl (Reldan) as the remaining surface application or admixed chemical options for storage pest control. Fumigation options have been limited to phosphine following the withdrawal of methyl bromide.
