TUBER VEGETABLES :: MINOR PESTS :: THRIPS

      These are tiny, slender, fragile insects. Adults have fringed wings. Both nymphs and adults scrape epidermal tissues of leaves usually near tips and rasp oozing sap. Affected tips get curled and dry up. Spray 0.2% carbaryl or 0.5% monocrotophos or thiometon to check pest population, if damage is severe.
