Only 3 farmers knew RKN…Read more about Root-knot Nematode may be a Hidden Problem in High Tunnels[Read More]

One year, I failed to manage insects, leading to a squash bug and cucumber beetle outbreak. The insects defoliated leaves (Figure 1) and caused cosmetic damage to…Read more about What Happened to the Winter Squash?[Read More]
Pumpkin and winter squash should be harvested fully mature to reach their optimal quality and fulfill their potential shelf life. Characters indicating fruit maturity include loss of rind surface gloss, ground spot yellowing, and hardening of the skin to the level that it is resistant to puncture with a thumbnail. Except for some striped varieties,…Read more about Tips for Harvest and Postharvest of Pumpkin and Winter Squash[Read More]
