Biological Control of Pests
The Adelaide and Mount Lofty Ranges NRM Board who funded the bio-control project through the Sustainable Industry Grants scheme were so pleased with the results that they have made a short movie with one of the growers - Hung Nguyen! Congratulations to Hung and the bio-control consultants who made this possible James Altmann (Biological Services), Lachlan Chilman (Manchil Services), and Steve Coventry (crop scout come rain, hail, heat or very late lunch).
Good Bugs Eat Big Pesticide Bill
Twenty farms in Virginia are now using biological control of key pests, including western flower thrips, spider mites, broad mites and green peach aphids.
Both farms had some degree of difficulty with the first planting due to TSWV infection, but fine tuning of the program has led to outstanding success. One farm is now successfully growing virus susceptible yellow capsicums with almost no losses. Sixteen farms are growing capsicum crops and two are growing cucumbers and two others involve tomato crops. Results are excellent with all pests (including Western Flower Thrips) on all farms and these growers will now adopt biological control across their whole farm Capsicum growers especially are noting that replacing insecticide sprays with bio-control agents is much kinder on the plants with healthier plants and higher yields of better quality fruit.
Where participating growers are still spraying some crops they note the plants are much weaker and are suffering heavy attack from Tomato Spotted Wilt Virus.
