Hi
I have a 4'X6' "greenhouse" that opens directly into my house. The 6 foot side is the one that is open to the house. I have had a nasty mealy bug problem and wonder if it is safe to use SucraShield under my green house conditions. The directions look like is us usually used for field crops. If I can use it how much should I put in a quart of water.

Jeanne,

I have used it in my greenhouse on a very varied collection of plants, and have seen no phytotoxicity issues at all. It does have a sweet, "icky" odor, but it passes quickly once the solution has dried.

It should be used at a rate of 1-1.25 ounces per gallon, so for a quart, 1.5 teaspoons is good.

I am glad there is no toxicity to the plants. How about to humans. Because there is no door to my "green house" the spray would drift into the living areas of the house. Would it pose a danger to us. It doesn't seem like it would based on its chemical components but I just want an opinion about it.

Personally, I think ALL chemicals should be treated as if they are hazardous.

SucraShield may not be toxic in the normal sense of the world, but it can be (fortunately temporarily) damaging to the eyes, so wear eye protection when using it. Once it's dry, there is no issue.

I don't know how large of a collection you are trying to treat, but might not a dunk be a better option?

That is a good idea. I have about 80 orchids. Most could be dunked in a five gallon bucket. It seems that would be more thorough too because it would get at the ones that might be in the roots. The rest I could take outside and spray. Thanks for the suggestion!
