One I didn't see and figured I'd pass on. I probably lost 15-20 pounds of tomatoes this year to a new (well, new for me) pest. Slugs. We have had a wetter than usual year, and slugs have been all over the garden eating tomatoes and green peppers (they leave the cayenne, jalapenos, and habeneros alone, and those formed a barrier to the potatoes, but they have wreaked destruction on the tomato crop.
Bury a plastic cup (or two nested cups) with the rims at ground level and put a couple of ounces of beer in the bottom. Slugs can't resist beer, and will crawl in and drown. These will have to be emptied every couple of days (hence the nested cups) and will stink, so when you check your traps, it is good to have some thin gloves on. Dump the sludge, replace the inside cup, and re-beer the trap. This will cut down on the amount of crop damage the little critters do.
