The strawberry clipper weevil is a significant insect pest of strawberry plants. It attacks the blossoms of the plant feeding on the sepals of the flowers. In the process of feeding, the insects frequently cut through the stem of the flower, effectively killing it. can dramatically impact strawberry yields, if left unchecked. The number of different insecticides are available to control clipper populations.
Insecticides Brigade and Danitol are recommended for treating clever weevils. They are pyrthroids, synthetic versions of the natural insecticide pyrthum. Unlike the natural version, the synthetic versions are stable in sunlight and effective against most insect pests including clippers. The active ingredient in Brigade is called bifenthrin, while fenpropathrin is the active ingredient in Danitol. Both are fourth generation pyrthroids and are currently available on the market.
Organophosphates are insecticides that contain phosphorus and among the most toxic and effective of insecticides, acting as a nerve agent. Organophosphates are very similar to gases used as chemical weapons and are the most toxic of insecticides to vertebrates. The organophosphate Lorsban is recommended for use against clipper weevils. Its primary ingredient is a chemical called clorpyrifos. Sniper is another organophosphate insecticide with the chemical acephate as its active ingredient.
Insecticides that contain carbon, hydrogen, and chlorine or refer to as organochlorines. DDT is perhaps the best known of organochlorines. Many organochlorines, including DDT, are no longer used in the United States for agricultural purposes. Methoxychlor, sold under the name Marlate, is the organochlorine insecticide of choice for combating clipper weevils.
