Tomato Pest & Disease Management Solutions
Tomato crops are susceptible to a variety of pests, diseases, and weeds that can significantly reduce yields and marketable fruit quality. At AcroTerra, we provide comprehensive pest and disease control solutions, including customized multi-active formulations.
Common Tomato Diseases & Protective Measures
Early Blight
(Alternaria solani)Common fungal disease producing target-board lesions on foliage and stems, causing severe defoliation and sunburn on exposed fruit.
- Circular, dark spots with concentric rings on lower leaves
- Yellowing foliage around lesions leading to leaf drop
- Collar rot on stems and dark leathery lesions at stem end of fruit
Seedling stage to early fruit development
Chlorothalonil, Mancozeb
Late Blight
(Phytophthora infestans)Destructive water mold that rapidly blights leaves, stems, and green fruit, causing brown rotting and potential total crop failure.
- Irregular dark green, water-soaked foliage lesions
- White mildew growth on leaf undersides under humid conditions
- Firm brown, wrinkled decay lesions on fruit rendering them unmarketable
Early to mid-fruit set stage, especially in humid or cool conditions
Metalaxyl, Mefenoxam
Common Tomato Pests & Field Interventions
Tomato Hornworm
(Helicoverpa zea / Manduca quinquemaculata)Large caterpillars that rapidly consume foliage and chew deep cavities into green and ripening fruit.
- Large feeding holes and ragged leaf margins
- Deep gouges and scars on developing fruit
- Defoliated branches with dark frass droppings beneath plants
Seedling through fruit setting
Permethrin, Spinosad, Chlorantraniliprole
Whiteflies
(Trialeurodes vaporariorum / Bemisia tabaci)Tiny sap-sucking pests that stunt plants, produce sticky honeydew, and transmit debilitating viruses like Tomato Yellow Leaf Curl Virus (TYLCV).
- Clouds of tiny white flying insects when plants are shaken
- Yellowing, cupping, and curling leaves with stunted vigor
- Sticky foliage covered with black sooty mold
Seedling emergence through harvest
Thiamethoxam, Imidacloprid, Spiromesifen
Critical Control Periods for Tomato
Seedling to Early Vegetative
Strict monitoring for early blight, flea beetles, and hornworm larvae
Flowering & Fruit Set
Preventative late blight management and whitefly vector suppression
Fruit Bulking to Harvest
Protect fruit integrity from fruitworms and blights while complying with Pre-Harvest Intervals
Mancozeb, Chlorothalonil, Metalaxyl, Mefenoxam
Permethrin, Spinosad, Thiamethoxam, Imidacloprid
