After pre-irrigation, cultivate shallow so that weed seed is not brought up from deeper soil layers. Maintaining deep furrows keeps the bed tops from becoming overly wet while maintaining adequate soil moisture for the crop (by keeping the bed tops drier, fewer weeds are likely to germinate in the soil surface). To avoid excessive competition with the onions and to make removal easier, cultivate when weeds are small. Hand weeding is a very efficient method for weed control. Use soil solarization. Cucurbits: Cucumbers, Squashes, Pumpkins, Melons, Watermelon Aphids (Several Use resistant varieties imidacloprid including melon or cotton Use regular monitoring with yellow sticky traps spirotetramat aphid, Pea Aphis gossypii, Sanitation: Field disking and destruction of crop residues are important for flupyradifurone aphid, Acyrthosiphon control of aphid pests of leafy vegetables to reduce their migration into nearby pisum) crops. If control is needed, treat when aphids are found to be reproducing, particularly when second and later generation wingless females have started reproduction. Aphid populations are easier to control before the plants begin to cup. Mangold flea beetle Use proper water and fertilization to grow vigorous plants and eliminate plant imidacloprid (Chaetocnema concinna) stress from insufficient moisture and powdery mildew.
