| Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production (see also chapter 1). Soil improvement, crop rotation, site selection, habitat management, variety choice, timing of planting and plant spacing are all considered before planting in order to avoid the most detrimental pest problems. Due to the huge variety of vegetable crops and their associated pest insects, specific tailored approaches are necessary. The effects of cultural practices to reduce pest outbreaks, such as weed control, appropriate irrigation, suitable fertilization, the use of mulches, and adjusted harvest times have been investigated during the last few years. For some crops (e.g. cabbage and... |

| Aphids and leafhoppers can cause heavy damage to sweet pepper (Capsicum annuum) and tomato (Solanum lycopersicum). Neem-Azal T/S was therefore evaluated in greenhouse experiments for leafhopper and aphid control. In 2005, five organic greenhouse compartments were treated with Neem-Azal T/S (0.2%, 1000-1500 L water ha-1; two treatments on tomato; three treatments on sweet pepper) for control of leafhoppers; four greenhouse compartments were left as untreated controls. Leafhopper flight activity was monitored using yellow sticky traps. Leaf damage was estimated by evaluating the fifth leaf from the top of the plant on 100 plants per plot. Flight activity was reduced by 80% (Abbott’s formula; 11-20 days after the 2nd treatment) to 93% (60-75 days after last... |
