Squash Bug and Squash Vine Borer: Organic Controls
Practical Farmers of Iowa has released a report discussing the results of on-farm research on control of squash vine borer. Two organic farmers who have both struggled with vine borers undertook a trial comparing five methods of organic control. Julia Slocum and Mark Quee compared organic methods to control squash vine borer in susceptible varieties of winter squash. They found that row cover was the most effective control practice, keeping more plants alive and producing higher yields. The trial also showed that Bt injections were effective at Quee’s but were much more labor-intensive than row cover. The full research report is available online.
