The stuff i have here is called BUG-X it kills when sprayed directly on the bugs. it can only be applied every 7-10 days but that doesnt help.. seeing what do i do about these bugs the rest of the 6 days in between?

is there any stuff that can be applied to the plants to keep the bugs away for a period of up to a week or even just a few days which wont harm the plants?

thanks

Warrior has a 3 week residual. Talstar's is 4 weeks. In the case of these two, the plants literally out-grow the treatment long before the chemical wears off.

What is the active ingredient in the material you're using?

Steve, I believe dave is using Permethri knockdown — 12.5g/L
from the link below.

Permethrin should give you 10-14 days of residual. Perhaps more depending on the rate applied. We have a Permethrin product here in the States that allows for insanely heavy rates for the control of Borers on trees. I wouldn't chance that rate on Pumpkins though. Leaf damage (phytotoxicity) would likely result.

What type of formulation are we talking about? Is that an Emulsifiable Concentrate (amber colored clear liquid) or a flowable (chalky/milky fluid)?

Maybe the insects are merely visable during the time they're picking up a toxic dose. Many chemicals kill insects even during those times they're not still acting as repellants.

We tend to watch what happens immediatly after a treatment. Wet spray residue of Permethrin would kill pests in the target area until the spray dries. If we come back later & find live pests, we might assume the product isn't working. Once dry however, the pest must ingest (eat) the residue to be controlled regardless what it is.

It isn't likely anything is going to kill insects within seconds unless it is still wet & is synergized with piperonyl butoxide (think about popular Wasp & Hornet aerosol sprays). Since none of the plant labeled insecticides are syngergized, they all take a while to kill the targetted pest.

How much feeding does it take before they're dead? If an unusually heavy pest outbreak has ocurred, even 98% control would appear to be a failure when in fact that is a very good result statistically.

Steve, it is a chalky/milky fluid. I have used the same product in different packaging last year. I am currently mixing at 20ml/Liter of water. Does it need to be reapplied after rainfall?

No. Not if it was dry. The new suspensions & micro-emulsions just don't wash off in rain. Sunlight is what finally does them in. Or the plant simply out grows the treatment.

What insect is Dave trying to control?

Not sure but it most likely is cucumber beetles. I think we should be ok. Your information has been a great help. Thanks Steve.

permethrin gets neutralized by sunlight in a few hours. good knock down though. Try spraying it on the dirt around your plants. It has a good residual in dirt.
