I used grub ex last year with poor results. I broadcast it and did not water it in. I have since read that it needs to be watered in. I also think I have read that it can be deactivated by the sun. Is this true? If I use it in 06 I think I will work it into the soil and water it in. I also seem to recall reading that it has to be used at high rates in order to translocate the insecticide to the vines & eventually the leaves. What constitutes a high rate? Going by memory I think a bag of grubex cost about $20 and covered 5000 sq. feet. I'll be growing 4 plants in 06 at 900 sq. ft. per plant. If I use one bag per plant would that be enough to get systemic activity? My cost would be $80 per treatment x 2 = $160. Would I be better off getting the Merit 75% powder from pumpkinsupply.com? If I read the site correctly 1 2oz. bottle would cover all 4 plants for about $50. At the recommended rate would the powder give me systemic activity? Two treatments would be about $100. So what do you think? I want to do this as inexpensively as possible but I want effective treatment too. Mark

go with merit you use ony about 2 tea spoons per gallon that doesn't even put a dent in 2 once bottle apply as a drench, and foliar with 4 plants you should have plenty for next year also, after applied to ground water it in. yu'll still see bugs but there just not feeding it was there last supper. or get scimtar from PumpkinSupply.com you wont have to wet under leafs, and goes a long way.

Grub-Ex is usually Imidacloprid (which is Merit) but it can also be Halofenozide in some states. Read the label to see which you have.
ALL forms of Imi8dacloprid must be watered in to work. The soil must then be kept evenly moist so the plant can translocate the active ingredient.
A seldom used trick is to add a small quantity of any soluble Nitrogen containing fertilizer to the Merit. The plants will scavenge the Nitrogen hungrily & pick up the Merit that much more efficiently & quickly.

I was thinking about growing a pumpkin on my side yard, just for the seeds...to eat. Will these chemicals contaminate the seed?

Admire (Imidacloprid) is labeled for use on human edible food cucurbit crops so no harm would come to the hogs. Imidacloprid travels only through vines & accumulates in leaves. Flowers & fruit never receive any part of the active ingredient when soil applied.
