Comments for REVIEW


mh comments 16.6.09: Pls check pestmodules on host plants (wheat empty) so that they contain crop-specific informaion and description incl. 'What to do'. Host-range in header should be more or less the same as the host range under General information. Structure of chapter General info): Geogr. distr, Introduction, Damage, Host range, Symptoms (missing), Affected Plant stages... etc (as on Armyworm) Cultural practices: Have reintroduced threshold examples (and also included in tomato and cotton) Kindly provide me with a copy of Negash and Abate paper. I cannot access it through internet or library. Further, if cucumber is a trap crop against whiteflies, it should be included under whiteflies. Pls provide reference. Pls check chapter on natural enemies: maybe this could be structured a little better. Pls include Ref for Bio-Re Project. (not bio-pe). If possible images of birds on perches and Setaria. Also the Intercropping/trap cropping chapter needs a bit structure, maybe take the trap cropping for cotton out or separate for cotton farmers. The info should also be included in cotton datasheet (and other crop datasheets/pestmodule where it makes sense). Pls check. Biopesticides: pls include detailled pest-specific recipes for the biopesticides provided - pepper, marigold, neem, bt, garlic, lantana, chillies, tephrosia. how, when, dosage, intervall. I have no access to these papers. Should the table be reintroduced? (its stored under point one, under note, not visible).
