Other claims from this paper (10)
- Intervention effect Bacillus thuringiensis spray deposits on cotton plants were protected for 4 days by adding 1% Coax, partially protected for 8 days.
- Intervention effect Adding 0.5% Coax to Bacillus thuringiensis spray deposits gave unsatisfactory protection.
- Intervention effect In cotton field plots, the B. th. preparation with Coax effectively controlled first to third instar Spodoptera littoralis larvae.
- Intervention effect Only 82% of fourth instar Spodoptera littoralis larvae were controlled in cotton field plots by the B. th. preparation with Coax.
- Intervention effect The chemical insecticide dursban gave results similar to the B. th. preparation with Coax.
- Intervention effect More larvae survived when Gustol was added to the B. th. preparation.
- Intervention effect Application of the B. th. preparation with Coax to alfalfa field plots was similarly effective in larval control.
- Intervention effect The B. th. preparation with Coax applied to alfalfa field plots increased alfalfa hay yield by 58%.
- Intervention effect Reducing the B.th. concentration from 1% to 0.33% slightly increased the number of surviving larvae.
- Intervention effect Further reduction of the B.th. concentration to 0.16% significantly reduced control effectiveness and yield increase.
