Is there any article that highlights increase in the insect population in the field to a pest status as a symptom of a larger problem of poor plant health or poor input management?
I feel our pest management strategies are more to manage the symptoms rather the addressing the root cause of the sub-optimal plant health status. For instance faulty N scheduling results in N accumulation in leaves and elevates sap suckers to pest status. Correction lies in nurturing a healthy plant rather than managing the symptom and leaving the host weak for further invasions? Similarly late season irrigation elevates pink bollworms. Stunted growth due to P and K deficiency results in shorter internodes, inviting more sucking pests Poor K status makes plants more susceptible to a variety of pests like whitefly, and we end up recommendation to manage the pest rather than correcting the plant health. Do healthy plants elicit in-built defence mechanisms?
Perhaps the entire philosophy of organic farming is based on plant health and defences, and creating an ecosystem favourable to plants and natural enemies rather than pests.
Has anyone used occurrence of certain pests as a diagnostic tool for plant health and offered corrections to rectify plant health rather than managing the pest.
