Pest management has been restricted to indiscriminate application of insecticides to foliage. Applying systemic insecticides to seeds has been shown to manage aphid infestations in other crop systems. We evaluated two commercially available seed treatments in East Africa, Apron Star (thiamethoxam 20 g\/kg + metalaxyl-M 20 g\/kg + difenoconazole 2 g\/kg) and Menceron (imidacloprid 233 g\/L + pencycuron 50 g\/L + thiram 107 g\/L) for their efficacy against M. persicae and impact on fresh leaf yield with two Amaranthus species, Amaranthus blitum (2 selections), Amaranthus hybridus (4 selections) and untreated control. Two storage periods (24 h and 3 months) with seed treatments were used. Each amaranth selection was treated individually with Apron and Monceren or untreated, and seeds were planted either 24 h or 3 months after treatment. Significant reduction in live aphids was observed with A. blitum and A. hybridus selections grown with seed treatment, at 6, 8 and 10 d after infestation (DAI) when compared with seeds grown without seed treatment. Untreated seeds of A. hybridus (selection 5) had significantly higher number of live aphids up to 243, greater percentage of damaged leaves and leaf damage score up to 84% and 64% respectively when compared with treated seeds of specific amaranth at 10 DAI. No significant difference was noted between seed treatment and storage time. Amaranth seeds treated with Monceren offered more protection against infestations of Myzus persicae than amaranth seeds treated with Apron under high tunnel experiments.<\/jats:p>","DOI":"10.1093\/ee\/nvad020","type":"journal-article","created":{"date-parts":[[2023,3,20]],"date-time":"2023-03-20T13:39:43Z","timestamp":1679319583000},"page":"360-370","source":"Crossref","is-referenced-by-count":1,"title":["Effects of seed treatments and storage duration on <i>Myzus persicae<\/i> (Hemiptera: Aphididae) and amaranth fresh leaf yield"],"prefix":"10.1093","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2388-6521","authenticated-orcid":false,"given":"Esther L","family":"Nampeera","sequence":"first","affiliation":[{"name":"Horticulture and Oil Palm Program, National Crops Resources Research Institute, NaCRRI , P.O.
