Pests Affecting Tomato Crops At The Vegetative Stage

As a farmer, you invest significant effort into nurturing your tomato plants from seed to maturity. However, even with utmost care, these plants remain susceptible to pests and insects that can undermine your hard work. In this article, we will explore common pests that target tomato crops during the vegetative stage and provide effective strategies to control and prevent infestations. 


Causal Organism: Thrips tabaci, Frankliniella sp. 


  • One pest that tomato growers often encounter is the thrips. These tiny insects feed on the young leaves of your tomato plants and cause damage. 
  • They can also transmit TOSPO virus, which can further harm your crops. 

Control Measures

  • Use Confidor Insecticide (Imidacloprid 17.8% SL) at the rate of 0.75-1 ml per liter of water. (Or) 
  • Spray Actara Insecticide (Thiamethoxam 25% WG) at the rate of 0.5 gm per liter of water. 


Causal Organism: Myzus persicae, Aphis gossypii 


  • Aphids are notorious sapsuckers, commonly infect tomato plants during the seedling stage. 
  • These small insects suck the sap of tender leaves, leading to misshapen and stunted growth. 

Control Measures

  • Use Sefina Insecticide (Afidopyropen 50 G/L DC) at the rate of 1 ml per liter of water. (Or)  
  • Spray Rogor Insecticide (Dimethoate 30% EC) at the rate of 1 ml per liter of water. 


Causal Organism: Tetranychus spp. 


  • These minute pests can cause yellow or whitish spotting on leaves, leading to weakened plant growth. 

Control Measures

  • Use Foster Insecticide (Cyflumetofen 20% SC) at the rate of 1 ml per liter of water. (Or) 
  • Spray Kunoichi Miticide (Cyenopyrafen 30%) at the rate of 0.3 to 0.5 ml per liter of water. 


Causal Organism: Bemisia tabaci 


  • Whiteflies also suck the sap from the tomato leaves. 
  • As a result of sucking, distorted and malformed leaves can be seen.  

Control Measures


Causal Organism: Maconellicoccus sp., Phenacoccus solenopsis 


  • Mealybugs are sap suckers, which suck the sap from the tomato plant and weaken them. 
  • They secrete a honeydew substance, which attracts other pests and can lead to the growth of sooty mould on the plant.  

Control Measures

Note: Taking proactive measures to control pests at the seedling stage is crucial for the successful growth of your tomato plants. Regularly monitor your plants for signs of pest damage and promptly intervene with the recommended insecticides. Remember to follow the instructions on the product labels and take appropriate safety precautions when using any pesticides.  


Effective pest control during the vegetative stage is crucial for successful tomato cultivation. By implementing these strategies and staying vigilant, you can ensure the health and vitality of your tomato crop.
