Seed treatments of rice against Aphelenchoides besseyi
In India, experiments were carried out to determine a seed treatment for rice seed to eliminate Aphelenchoides besseyi (EPPO A2 organism) without affecting the viability of the seed.
Two treatments induced a 100% mortality of the white-tip nematode:
- seeds were soaked in a 0.2% solution of mancozeb and monocrotophos and subsequently subjected to a vacuum fumigation (methyl-bromide ca 32 gm-3) for 2 h at 30° C
- same soaking procedure as in 1. but the vacuum fumigation was substituted by an atmospheric fumigation (aluminium phosphide ca 9,3 gm-3).
