Use of Chitin for Controlling Heterodera avenae and Tylenchulus semipenetrans.
The nematicidal effect of chitin, relative to other pesticides, was evaluated against two plant-parasitic nematodes, Heterodera avenae and Tylenchulus semipenetrans. Wheat seedlings, grown in soils artificially or naturally infested with H. avenae, were treated with 0.4% (w/w) ClandoSan (CLA) prepared from crustacean chitin, aldicarb (Temik 15G), or ethylene dibromide (EDB 90EC). The CLA treatm...
متن کاملFactors Influencing Emergence of Juveniles from Cysts of Heterodera zeae.
Several factors were studied to determine their effects on hatch and emergence of second-stage juveniles (J2) from cysts of Heterodera zeae. The optimum temperature for emergence of J2 from cysts of H. zeae was 30 C. No juveniles emerged from cysts at 10 or 40 C. Immersion of cysts in 4 mM zinc chloride solution stimulated 10% greater emergence of J2 than occurred in tap water controls during 2...
