| MAJOR PESTS | ||
|---|---|---|
| Insects | Diseases | Weeds |
| European corn borer | Bacterial leaf spot (BLS) | broadleaves |
| Green peach aphid | Phytophthora | annual grasses |
| Corn earworm | Cucumber mosaic virus | perennials |
| Tomato spotted wilt virus | ||
| Anthracnose | ||
| A. Site Preparation | Priority | Points | Acreage Goal |
|---|---|---|---|
| 1) Review weed map/list of fields to choose appropriate weed control strategies. See the Weed Assessment List available for use in satisfying this element. | M | 5 | 75% |
| 2) Crop Rotation. Plant only in fields where peppers, tomatoes, or cucurbits have not been grown in the previous two years to avoid carryover of disease inoculum | H | 10 | 50% |
| 3) Maintain good soil drainage or plant on raised beds to avoid Phytophthora crown and fruit rot | M | 5 | 50% |
| 4) Soil test at least every three years; fertilize according to recommendation | H | 10 | 100% |
| 5) Plant on plastic mulch with trickle irrigation for weed control and to minimize disease spread | M | 5 | 50% |
| B. For growers producing their own Transplants | |||
| 1) On BLS susceptible varieties: use sodium hypochlorite or hot water treated seed to avoid seed-borne inoculum | L | 3 | 10% |
| 2) Use fungicide treated seed for control of damping-off pathogens | H | 10 | 50% |
| C. Variety Selection | |||
| 1) Use tolerant or resistant varieties whenever possible for controlling bacterial leafspot and viruses | H | 10 | 50% |
| D. Planting | |||
| 1) If using fertigation, apply no more than 50 lb. N at planting and the rest in two or more split applications | M | 5 | 25% |
| E. Pest Monitoring and Forecasting | |||
| 1) >Scout to determine the need for cultivation or post-emergent herbicide | L | 3 | 50% |
| 2) Monitor flights of E and Z race ECB and CEW on your farm using recommended pheromone traps and lures or use extension pheromone trap network information. | H | 10 | 100% |
| 3) Scout as recommended for aphids | H | 10 | 100% |
| F. Pest Management | |||
| 1) Calibrate sprayer(s) annually or more frequently as needed. | H | 10 | 100% |
| 2) Use recommended action thresholds for making decisions about applying pesticides for insects and diseases of importance. | H | 10 | 100% |
| 2) Time sprays for European corn borer to peak moth flights after fruit reach walnut size | H | 10 | 75% |
| 3) Choose effective pesticides that have the lowest environmental impact based on overall EIQ. OR Choose effective pesticides that preserve natural enemies based on natural enemy component of EIQ. | M | 5 | 50% |
| 4) Keep records of pest densities, pesticide applications, cultural pest management practices, and biological control techniques used. | H | 10 | 100% |
| 5) If using plastic mulch, cultivate between beds for weed control | L | 3 | 25% |
| 6) Optional: if planting on plastic, plant a cover crop in the aisles for weed control | M | 5 | 10% |
| G. POST HARVEST | |||
| 1) Update weed map/list after harvest to use when planning for next year. See the Weed Assessment List available for use in satisfying this element. | M | 5 | 75% |
| 2) If needed, spot treat perennial weeds with a translocatable herbicide. | L | 3 | 25% |
| 3) Pull and landfill plastic mulch if it was used or re-use for additional season(s) | H | 10 | 75% |
| 4) Disk down crop residue if not re-using plastic mulch | M | 5 | 50% |
| 5) If harvest ends by October 1st establish cover crops for weed control and to scavenge leachable nitrates. | H | 10 | 50% |
