Bayer Outdoor Fruit & Vegetable Insect Control Liquid Insecticide, 32 fl oz

I have used this product for my citrus and apples trees in Orange County, CA for 13 years to treat white flies and leaf miners. I also used Bioadvanced Tree and Shrub Protect and Feed for about 5 years to kill capillaries on my Red Bud trees. Both of these two products were amazing to eliminates these insects on my fruit and Red Bud trees. I have tried many different spraying products but could not eliminate those insects. Besides that, my trees were 10 to 15 feet tall that made spraying extremely difficult. The two Bioadvanced products above were miracles and helped me to relieve headaches and nightmare to deal with insect every year at spring/summer times. However, last month, I have tried to buy these Bioadvanced products again for this year but were very shocked when learning that California banned of selling them. The nightmare is coming back again. Without these products, I may run out of choice but to chop all my trees and plant plastic plants instead!!! Question to Bioadvanced: Because California and also a few more states banned Imidacloprid, Do you have other (or new) systemic products (Not spray products) available with other ingredients than Imidacloprid that have the same effectiveness as these two BIoacvanced items that I described above?

I have used this product successfully here in N San Diego County, CA for many years on all my citrus trees. I find it is no longer available in local stores or for online ordering. Is there some type of governmental ban?
