Control de Plagas
Lemons (Citrus limon Burm.) were evaluated for their tolerance to carbonyl sulfide (COS) fumigation and the influence of COS on market quality. At 70 mg l-1 no significant deleterious changes occurred in market quality up to a fumigation duration of 8 h and only a slight amount of peel injury was observed after 12 h. Longer fumigations lead to the presence of an offensive off-odor in the juice as well as to increasing rind injury.

Combined Efficacy of Biofertilizer with Different Biopesticides on Aphid’s Infestation (Acyrnthosiphon pisum) and the Productivity of Pea Crop (Pisum sativum)
Sweet corn is a crop that lends itself well to small-scale and part-time farming operations. Initial investment is relatively low, and many field operations - such as land preparation, planting, and harvesting - can be custom-hired. Equipment needs on a small-acreage farm are not very great, and most of the equipment can be used for other purposes.
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.
