Herbicide injury to plants can result from misuse or misapplication of herbicide used in yards and gardens. Damage from herbicide Soil sterilants are often used around driveways, fences, or sidewalks to stop all weed growth. Identifying nontarget crop and ornamental plant damage or injury from herbicides has become much easier. Dr. Kassim Al-Khatib, weed science professor at UC Davis and director of the UC Statewide Integrated Pest Management Program (UC IPM), has gathered nearly a thousand photos of herbicide-damaged plants, drawn from his own and others’ research.
Interveinal chlorosis is a symptom of a micronutrient problem, and your plants are lacking in zinc, iron, sulphur or magnesium. A micronutrient issue is likely to be caused by a pH imbalance rather than a lack of it in the medium (if feeding correctly).
