Hello. Do you sell anything that I can use to treat Thrip and Scale? I believe we have the Maskell scale on my black or Japanese Pines and would like to get something that can handle both insects.
First, you are wise to treat this problem. If left to do as they wish, they will deplete vital resources from their host trees most certainly leading to undue stress, disease and other complications. Second, you should be able to successfully handle both pests using the same material.
In our SCALE CONTROL article you’ll note a product listed listed as BIFEN; this will work well for both scale and thrips. Be sure to add some SPREADER STICKER to the tank mix which is vital for the Scale since they tend to be somewhat protected in plant stems where the application will many times not reach them nearly enough.
