Vegetables

• Overview: Wet weather conditions have continued and crops in low areas of fields are showing some wet soil related stresses.  Bacterial disease incidence is increasing.  Japanese beetles have shown up and are feeding on a number of vegetable and fruit crops.
• Tomatoes: Bacterial diseases (bacterial spot and bacterial canker) in field grown tomatoes are showing up with more frequency.   Early blight and septoria leaf spot are also being found in fields.  In high tunnel tomatoes, scouts continue to find timber rot and botrytis.  Variegated climbing cutworm damage to fruit has been observed in some high tunnels.
• Sweet Corn:  Some plantings are at silk stage this week.  European corn borer moth catches in traps continues to be high and corn borer damage in sweet corn has ranged from 2 to 30%.  Corn near or at silk is being sprayed to prevent corn borer damage.  No corn earworm moths have been caught in traps yet.
• Potatoes:  Most are in bloom.  Potato leaf hopper (PLH) counts have been low.  Colorado potato beetle (CPB) pressure continues.  Some low incidence of potato black leg, a bacterial disease has been found in one grower field (photo by Chris Smedley attached).
• Eggplant generally looks good but growers are experiencing heavy CPB numbers in some plantings.
• Green/snap beans are ready to harvest in some fields and generally look good.  There has been some light damage levels due to bean leaf beetle, grasshopper and Japanese beetle feeding.
• Onions are forming bulbs and pushing up against plastic soil covers.  Thrip damage has remained light.
• Cabbage is forming heads and overall looking very good.  Some fields have cabbage worms above threshold levels.
• Winter squash and pumpkins are in bloom and vines are running.  Angular leaf spot can be found along with light feeding damage by cucumber beetles and Japanese beetles.  One of the bigger issues is weed control.  The wet weather is preventing timely cultivation.
• Zucchini and summer squash are ready to harvest in some fields.  Similar to winter squash and pumpkins, angular leaf spot is present in many plantings.
• Cucumbers are approaching harvest in some fields and the crop looks good.
• Japanese beetles were found in numbers and feeding damage above threshold levels in some black raspberries and were also found in lower numbers in some grape vines.

VEGETABLES:

• Cole crops: Cabbage, Cauliflower and Broccoli:  Most cole crops look good.  Imported cabbage worm larvae were found in some fields at economic treatment threshold levels.  Flea beetle damage and numbers were noted at mostly low levels.
• Onions and Garlic: Thrips are generally present but at low levels, well below threshold.
• Peas:  Doing well at this time with no problems noted.
• High tunnel tomatoes:  Botrytis, early blight, pith necrosis and timber rot/white mold diseases were noted by scouts along with tobacco spotted wilt virus (vectored by thrips) noted on some cherry tomatoes.
• Field tomatoes:  Most tomatoes looking good at this point.  Some early blight was found and a sample submitted for possible bacterial spot diagnosis.
• Sweet corn: Corn tasseling beginning in some fields. Corn borer damage was noted, still below economic treatment threshold.  Corn borer moths are being caught in pheromone traps.  Armyworm damage was found at light levels.
• Cucumbers:  Cucumber beetles being found.  Several fields over economic treatment threshold.  Angular leaf spot, a bacterial disease, is appearing on some plants.
• Zucchini and Summer Squash:  Cucumber beetles at threshold in some fields.  Scouts noted angular leaf spot, and anthracnose diseases, also some blossom end rot.
• Winter Squash and Pumpkins:  Cucumber beetles were found over economic threshold level in some fields.  Some light slug feeding was also noted.
• Melons: Anthracnose and bacterial wilt have been found.  Some melons had cucumber beetles over economic threshold.  Some light slug feeding was found.
• Potatoes:  Colorado potato beetles (CPB) are being found in moderate to heavy numbers, eggs, larvae and adult forms.  Many potatoes have CPB over economic threshold and are spraying for control.
• Peppers: Most peppers looking good. Scouts did note some light feeding by flea beetles on some plants.
• Eggplant: Potato leaf hopper (PLH), CPB, and flea beetles were all found on eggplant.  All three insects were found in some planting s over economic treatment level.
• Green/Snap Beans:  Some anthracnose was noted on green beans.  Slug feeding, bean leaf beetle feeding damage were noted at light levels in some plantings.  Grasshoppers were found at small numbers.  PLH were noted at above economic treatment threshold in some plantings.
