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).

Spores spread to healthy tomato leaves by windblown water, splashing rain, irrigation, mechanical transmission, and through the activities of insects such as beetles, tomato worms, and aphids. [1] Provided the environment is conducive for disease development, lesions usually develop within 5 days of infection.
The ecology of the different species, their interactions, relationship to the host are little understood. A chance observation of a Microcyclospora tardicrescens inhibiting the growth of the fruit pathogen Colletotrichum fioriniae in dual culture tests, yielded trichothecolone acetate and its (S)-7-hydroxy derivative as active principles for the interaction between M. tardicrescens and C ...
Entomopathogenic fungi, which cause disease in insects, include at least 14 species that attack aphids. [77] Beauveria bassiana is mass-produced and used to manage a wide variety of insect pests including whiteflies , thrips , aphids and weevils . [ 78 ]
Because PRSV is a non-persistent virus and is consequently transmitted to healthy plants by aphids within a very short time period, insecticidal control is difficult and impractical. Once symptoms have been observed, it is already too late to spray for aphids – the disease has most likely already been transmitted to nearby healthy plants.
