An aphid infestation can ruin a garden. Learn what causes aphids and how to identify, kill, and control them naturally for healthy plants with no aphid holes.
Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
Aphids can also transmit viruses and allow sooty mold to take hold. When the population becomes too large, an aphid might grow wings and fly away to find a fresh host plant.
Aphids do best when amino acids are actively translocated in the phloem. In spring, the leaves grow and import amino acids via the phloem; in summer leaves are mature and export mainly sugars. In autumn, the leaves senesce and export amino acids and other nutrients. Thus on trees the leaves are most suitable for aphids in spring and autumn.
It may be due in part to the aphids subterranean habitat or unknown influence on overall plant fitness. [7] In terms of economic importance, crops such as rice, barley, wheat, potato, tomato, plum, and apricot top the list. [8] R. rufiabdominale is considered one of the most abundant aphids affecting wheat and grain crops in the United States. [25]
