Dry Beans
Year-Round IPM Program for Dry Beans
(Reviewed: 12/08, Updated 12/08)
These practices are recommended for a monitoring-based IPM program that
reduces environmental quality problems related to pesticide use. Links take
you to information on how to monitor, forms to use, and management practices.
Track your progress through the year with the annual
checklist form.
Water quality becomes impaired when pesticides move off-site and into
water. Air quality becomes impaired when volatile organic compounds move
into the atmosphere. Each time a pesticide application is considered, review
the Pesticide
Application Checklist at
the bottom of this page for information on how to minimize environmental
quality problems.
This program covers the major pests of blackeye, common,
and lima beans in the Central Valley. Information on additional pests is
included in the Dry Beans Pest Management
Guideline.
| What should you be doing at this time? |
Survey weeds in the current crop.
Manage weeds before planting within and adjacent to the field. |
Select field considering:
- Pest history (including current crop):
- Weeds
- Diseases
- Insects
- Nematodes
- Surrounding crops and vegetation.
- Soil conditions and water quality.
- Crop rotation.
|
Select the cultivar. Consider
treated seed for fields with a history of:
|
Calculate nitrogen budget and inoculate seed with
appropriate Rhizobium bacteria. |
| Prepare the field for planting, including laser leveling
to correct drainage and runoff problems as needed. |
Planting
to stand establishment
|
| What should you be doing at this time? |
Consider seed handling and planting techniques
that:
- Reduce cracking and splitting of seeds.
- Ensure appropriate planting depth, maximizing germination rate and
reducing risk of seedling diseases.
|
Inspect seedlings for
damage. Manage if needed
according to the PMGs. |
| Manage irrigation. |
Survey weeds 4 weeks after planting.
Cultivate beans to remove weeds, as necessary. |
| Calculate nitrogen budget. |
Vegetative
growth to flower bud
|
| What should you be doing at this time? |
Continue sweep
net sampling for lygus bugs.
Manage if needed according to PMG. |
Continue looking for pests
or their damage on a
weekly basis. Manage if needed according to PMG. |
Survey weeds before harvest.
Remove nightshade plants if necessary. |
| What should you be doing at this time? |
| Adjust combine to reduce mechanical damage and bean
loss. |
| Exercise care when threshing to ensure moisture content
of seed below 15%. |
| What should you be doing at this time? |
Carry out sanitation
practices in the field to
reduce the spread of:
- Weeds
- Diseases
- Nematodes
- Insects
|
Pesticide application checklist |
When planning for possible pesticide applications in an IPM program,
review and complete this checklist to consider practices that minimize
environmental and efficacy problems.
- Choose a pesticide from the UC IPM Pest Management
Guidelines for the target pest considering:
- Consider water
management practices that
reduce pesticide movement off-site:
- Choose sprayers and application procedures that
keep pesticides on target.
- Identify and take special care to protect sensitive
areas (for example, waterways or riparian areas) surrounding your
application site.
- Review and follow label for pesticide handling,
storage, and disposal guidelines.
- Check and follow restricted entry intervals (REI)
and preharvest intervals (PHI).
- After an application is made, record application
date, product used, rate, and location of application. Follow up
to confirm that treatment was effective.
- Install an irrigation recirculation or storage
and tail water return system. (See Reducing
Runoff from Irrigated Lands: Tailwater Return Systems .
- Limit irrigation to amount
required using soil moisture monitoring and
evapotranspiration (ET).
- Consider vegetative
filter strips or ditches.
- Install sediment traps.
- Use polyacrylamide (PAM) tablets
in furrows to prevent off-site movement of sediments.
- Redesign inlets and outlets into tailwater ditches
to reduce erosion.
- Consider management practices that reduce air quality
problems.
- When possible, choose pesticides that are not in emulsifiable
concentrate (EC) form which release volatile organic compounds
(VOCs). VOCs react with sunlight to form ozone, a major air pollutant.
