Abstract
Nursery tests showed that aqueous sprays of a 25% diflubenzuron (DFB) W.P. at 0.007%, 0.009%, 0.011% and 0.013% a.i., a 2% neem seed kernel suspension (NSKS) in water and a combination of 1% NSKS plus 0.0035% DFB protected tobacco seedlings from tobacco caterpillar (Spodoptera litura [F.]) damage up to 9 days after spraying. Weekly treatments in a bulk nursery with 0.009% DFB and 2% NSKS commencing 4 weeks after germination and continued for 7 weeks, offered significant protection and significantly reducedS. litura larval population compared with an unprotected nursery.
