AI Article Synopsis
- Neem and mata-raton leaf extracts were tested as insect repellents in organic tomato cultivation, comparing their effectiveness to untreated plants and a chemical treatment (lambda-cyhalothrin).
- The best tomato plant growth was observed with Gliricidia (mata-raton) treatment, while differences were minor in the other treatments.
- Gliricidia leaf extract not only enhanced tomato growth and altered leaf and fruit characteristics, but its effects were attributed to growth regulation rather than insect repellent properties.
Article Abstract
Extracts of neem (Azadirachta indica A.) and mata-raton (Gliricidia sepium) leaves were used as insect repellent during organic cultivation of tomato plants (Solanum lycopersicum) and were compared with untreated plants or plants treated with lambda-cyhalothrin (chemical treatment). The best developed tomato plants were found in the Gliricidia treatment, while difference between other treatments were small. The number of different species of macrofauna found on tomato plants were similar in different treatments, except for corn rootworm (Diabrotica spp.) found in the Gliricidia treatment, but not in other treatments. It was found that leaf extract of G. sepium stimulated tomato growth and altered the leaf and fruit characteristics. This was most likely due to its action as a growth regulator and/or an inductor of changes in the tomato growth regulation, but not due to its action as an insect repellent. Consequently, leaf extract of G. sepium could be used to stimulate tomato development.
