Old plantings of tomatoes, peppers and other host crops should be removed from the garden at the end of the year and composted or placed in the trash. Injuries are produced from the effects of saliva introduced as the insect feeds, causing a range of symptoms that are often described as “psyllid yellows”. Insecticidal soap, made from potassium salt of fatty acids, works by penetrating and destroying the outer shell or membrane of the insect causing it to dehydrate and die.
