- Corn and Soybeans: Planting just starting, some corn had sprouted but not yet emerged.
- Alfalfa: Scouts noted alfalfa weevils at first through 3rd instar larval stages. Numbers are higher than the previous week but below threshold level. Alfalfa height noted between 9 to 22 inches.
- Asparagus: Scouts are noting the presence of both asparagus beetles and eggs.
- Cole crops: Cabbage, Cauliflower and Broccoli: Scouts noted the presence of light to moderate levels of flea beetles in some plantings and also detected a few eggs of the imported cabbage worm on some plants.
- Onions and Garlic: Scouts noted the presence of thrips below threshold level on some plants.
- Peas: Doing well at this time with no problems noted.
- High tunnel tomatoes: Scouts reporting tomatoes at bud, bloom and fruit set stage of development. The warmer temperatures since the last scouting visit helped the tomatoes to look better at all locations.
- Sweet corn planted under row cover or early field planted: ranged in size from just spiking through the soil surface to 6 inches tall on some row covered sweet corn. Some light slug damage observed by scouts in sweet corn under row cover.
- Cucumbers: Scouts noted cucumbers in high tunnels at bloom and fruit set stage and other cucumbers planted under row cover approaching bloom stage of development.
→ Other crops noted as planted under row cover include green beans, melons, squash.
- Potatoes: Planted, scouts noted most starting to emerge.
- Apples: Codling moth trap numbers increased and in several orchards averaged 3 or more moths per trap. A bio-fix date has been set as May 12. Growing degree days (GDD) are being tracked to determine when pesticide application needs to be made to control codling moth larvae. Depending upon variety, apple stage of development ranged from bloom to petal fall.
- Peaches: Scouts are continuing to note winter damage. Most trees do not have blossoms. A few trees have a couple of blossoms. Oriental fruit moth catches were very high. A bio-fix date of May 7 was set. GDD are being tracked.
- Strawberries: Scouts noted strawberries are in bloom. It is important to use fungicides during the infective bloom period to prevent botrytis gray mold of strawberry fruit. Scouts also noted a few spittle bugs and some leaf spot on strawberry plants.
- Grapes: Scouts noting some cluster development. Early season fungicide spray for control of grape black rot and phomopsis cane blight needs to continue.
- Brambles, Blackberries and Raspberries: Scouts noted the presence of the lesser carpenter bee, which bores into bramble canes. Scouts are watching for orange rust.
Blueberries: Most plants are in full bloom. Scouts noted yellow leaves in one planting. Very probably the yellow leaves are related to soil pH being too high.

- Codling moth trap numbers were low across all orchards. No bio-fix date has been set. Depending upon variety, apple stage of development ranged from bud to pink to bloom starting.
- Scouts are continuing to note winter damage. Most trees do not have blossoms. A few trees have a couple of blossoms. Monitoring for oriental fruit moth began this week.
- Scouts noted that some strawberries were starting to bloom.
- Scouts noting some winter injury and winter kill on some vines. Other vines are beginning to bud and leaf out. Early season fungicide spray for control of grape black rot and phomopsis cane blight will need to begin at the 1-3 inch shoot growth stage.
Brambles, Blackberries and Raspberries:
- Scouts are seeing winter kill back to the soil level on thornless black berries. Thorny type blackberries and all raspberries are leafing out normally.
- Some varieties are starting to bloom. Scouts noted yellow leaves in one planting. Very probably the yellow leaves are related to soil pH being too high.
