I was providing training to extension plant protection specialists in Malawi last October, under USAID funding, and we developed a list of pesticides that were efficacious and lower risk. Not all of these are available in Malawi and I would be pleased to expand on this answer if needed.
I'm sorry I am not using trade names, but can add local Malawi trade names if needed.
The list of pesticides that only require baseline protective clothing (i.e. long sleeved shirt, long pants, stout shoes and gloves) is as follows:
Azadirachta indica (neem which can be locally produced), Bacillus thuringiensis (subsp. Aizawai), chlorantraniliprole, flubendiamide,
methoxyfenozide, SfNPV, pyrethrum
PLEASE NOTE: the widely available formulations of profenofos and chlorpyrifos are far too toxic to humans to be used, and there is evidence that cypermethrin and other pyrethroids that are used against African armyworm, are not effective against fall armyworm.
Details of this work can soon be found in an Open Source publication: Jepson, P.C., Murray, K., Bach, O., Bonilla, M.A., Neumeister, L. (2020) Selection of pesticides to reduce human and environmental health risks: a global guideline and minimum pesticides list. Lancet Planetary Health 2020; 4:e???-??? (in press, February Edition)
