Microbiological Contamination Linked to Implementation of Good Agricultural Practices in the Production of Organic Lettuce in Southern Brazil
Interviews were conducted with the owners of three organic lettuce farms in the state of Rio Grande do Sul in southern Brazil using a standardized self-assessment questionnaire to ascertain the status of implementation of good agricultural practices and management systems in place.
A Comparative Study of Composition and Postharvest Performance of Organically and Conventionally Grown Kiwifruits
Postharvest performance of organic and conventional ‘Hayward’ kiwifruits grown on the same farm in Marysville, California, and harvested at the same maturity stage were compared in this study. Quality parameters monitored included morphological (shape index) and physical (peel characteristics) attributes of the initial samples.
Effect of Organic Osmolytes on Pea Seed Yield under Drought Stress Conditions Imposed at Different Growth Stages
USDA-NOP: considered nonsynthetic, allowed. Preventive, cultural,
mechanical and physical methods must be first choice for pest control, and
conditions for use of a biological material must be documented in the
organic system plan (7CFR 205.206(e)). The National Organic Standards
Board reviewed this substance in May, 2002 and found it to be a permitted
nonsynthetic substance (USDA 2002).
USDA - NOP STATUS: Allowed for use as insecticide, miticide, algicide,
and moss killer. Ammonium soaps are permitted as animal repellants
provided there is no contact with edible portion of crop or with soil. Soap is
not currently permitted for use as a fungicide or herbicide. (NOP 2000).
The USDA-NOP regulation does not describe the type of soaps permitted,
though the initial review was for potassium salts of fatty acids. Soaps
classed by EPA as List 4 inerts (inerts of minimal concern) may be used as
inert ingredients and adjuvants.
- Selection of suitable cultivars.
- Proper preparation of cuttings and planting.
- Enhancement of soil fertility to improve yields.
- Increasing plant persistence against pests, diseases and weeds.
- Harvest and proper storage.
- Why certify your products as organic?
- Which certification system do I need?
- Step 1: Conversion planning
- Step 2: Decision to pursue certification
- Step 3: Application and agreement
- Step 4: Recordkeeping
- Step 5: Annual inspection
- Step 6: Certification
Interest in nonchemical pest control has increased over the past several years. To some people, this means the same as “organic farming,” which implies nature’s way. But in this publication, we talk about controlling pests without chemicals, or at least fewer chemicals. This approach does have some limitations. Here are some of them:
