Cucurbit yellow vine an important disease of cucurbits. Squash, pumpkin, watermelon and cantaloupe may be affected. Symptoms usually occur just before fruit maturity. Plants may be stunted and yellow. Squash vine borer may cause a squash or pumpkin vine to wilt and decline. Vines or plants that have wilted due to squash vine borer will have white larvae inside the lower stem that may be as big as a thumb.
  4. Curing and storage of onions. It won't be long until we are harvesting our storage onions. Good curing is essential for long-term storage of onions. Curing involves exposing the onions to mild temperatures in a dry, well-ventilated area. There are several ways to cure onions. One method is to spread the onions in a single layer over screens (these can be made by simply attaching chicken wire to a wooden frame) in a shaded and well-ventilated area. This can be outdoors but the onions should be covered with a tarp if rain threatens. Curing takes about two to three weeks. After onions have been cured, cut the tops back to a length of about one inch. DO NOT remove the dry, scaly skins from onions, shallots, or garlic when storing.
  5. Pumpkin Insect Management. This link is to a factsheet from Dr. Weinzieril on identification and management of pumpkin insects. It is from 2003 but is still relevant today.
