Can Bayer Insect/Mite Control also be used as a soil drench on brugs?

Can Bayer Advanced Insect, Disease and Mite Control concentrate* used as a diluted soil drench? I contacted Bayer but the representative simply read off the label and said it's meant to be used as a spray and can't guarantee its effectiveness as a soil drench. Has anyone used this popular product as a soil drench? Is there something about the formulation that only allows it to be effective as a foliage spray? I would like to use this both as a foilage spray and a soil drench so that I can kill pests on contact and also have the plant internalize the insecticide/miticide.

Some background: my brugmansia is being attacked by all kinds of pests from red spider mites, whitefly, caterpillars, earwigs, and other leaf-eating insects. I've tried insecticidal soap with very limited success (this might have to do with the fact that I can't keep up with the spraying schedule). While the damage is mostly cosmetic for now, the damage is getting worse each week. It's becoming too painful to look at every time I pass by them in my garden. I would like to stem the infestation to a point where beneficial insects can keep these pests under control.

Unless you can find directions for applying as a drench somewhere on that label, you can't use it in that manner. This formulation contains three very agressive active ingredients....you should look up each one to see how they work. It's different than other imidacloprid formulations.

The primary issue with this product is that you are clearly and specifically warned against using it when your plant is flowering. Not just when bees are foraging but when your plants are flowering!

The label cautionary statements also clearly warn about avoiding run-off and any contact with surface waters.

I used to teach landscape and horticultural professionals to properly use pesticides. The first step is to carefully read the label to evaluate whether or not the product is suitable for the required use.

This chemical doesn't pass, does it?

It's not our job to try to find ways to go off label and then justify it but to use good, common sense and information gathering to come up with safe, effective, and appropriate methods of control.

If the label deoes not say the product is a soil drench it cannot, legally, be used for that. The label says "It is a violation of Federal Law to use this product in a manner inconsistent with the label".

Banner Maxx substitute? And 3-in-1 Insect, Disease & Mite Control
Q

Spider mites can quickly build up an immunity to even the more expensive remedies (AVID). I'd hate to see what they do with something that requires you to spray every 7 days in order to get the fungicide protection. Before I incorporated Banner Maxx into my spray shedule I had used only Orthos Fungunex (active ingredient is Triflorene-now named "Ortho Rose Pride- Rose and shrub disease control"). It was and is still very effective. The only advantage that I can see with BM over Fungunex is the length of time between sprayings. In fact I really feel that in the early spring Fungunex is a better choice. As for the Bayer products, I can't say they aren't good, I'm just saying that Fungunex (Triflorene) did such a good job for me that I never needed to try anything else.

Bayer adv disease control

I use the Disease Control product as a spray as needed. Most of the fungal problems I have crop up in the winter while its wet. Frequent spraying (2-3 weeks) helps control the disfiguring black spots. I probably won't be using it again until winter. I noticed that there was none of the old B T&S at OSH recently. There were several new formulations for trees and shrubs, and lawns, some containing different amount of fertilizers. It looks like Bayer Tree and Shrub Landscape formula is the way to go. It is twice as concentrated as before (now 2.94% imidacloprid), so use 1/2 ounce, 1 tablespoon per gallon. Another good product, although relatively expensive to use, is Bayer 3-in-1 Insect, Disease, and Mite control. Use as directed on the label. Most of the time, I don't need the 3-way treatment, and it is cheaper to use the single ingredient products

Can Bayer's Insect and Mite Control also be used as a soil drench?

There are numerous formulations in which imidacloprid is used. This particular product contains other active ingredients that need to be considered before deciding to go off label. First Time, a pesticide user user MUST take the product label seriously. If we don't understand what we're reading, it is not up to us to 'interpret' that document to use it the way we want to. This particular pesticide is not to be used as a soil drench. Take it back to the store and get something that works better for you.

Only if the label permits it. So, I guess not.

I was taught the label is the law.

Would it be cheaper to throw it out and plant something else there?
