Integrated Approach for Management of Leaf Miners in Crops
Leaf miner is one of the serious pests that attack a wide range of crops including vegetables, fruits, ornamentals and cause economic yield loss. Larva is the attacking stage of the pest that causes damage to leaf tissues, reducing photosynthesis and ultimately reducing the yield and quality of crops. They are typically small maggots that range in colour from yellow to green or brown. They have piercing and sucking type of mouthpart that allows them to scrape and feed on the plant’s tissue. The feeding activity of the larvae creates distinctive trails or tunnels on the surface of the leaf, which can vary in shape and size depending on the species of leaf miner.
Leaf miner infestation can cause significant damage to crops affecting their growth and yield. Effective management of leaf miners requires timely detection and a combination of several control measures to reduce their impact on the crop.
Leaf miners infest a wide range of plants, including vegetables, fruits and ornamentals. Tomato, potato, okra, citrus, spinach, pepper, peas, beans, beets, cucurbits and crucifereous vegetables are the commonly affected crops.
Warm temperature, high humidity, presence of host crops, monoculture cropping, presence of plant debris, excessive use of pesticides can favour leaf miner infestation.

(NOTE: Presence of eggs and larvae in leaf, pupae in soil and adult on plants are needed to be killed in integrated methods for effective control of leaf miners. Insecticides with translaminar or systemic mode of action can be used to control leaf miner. Please check the product label before use to know the right time of application)
Leaf miner can cause reduced plant growth, reduced yield and premature leaf drop which can affect the overall productivity of the crop. Integrated management of leaf miners in crops involves a combination of preventive and management measures that can effectively control leaf miner infestations and minimize crop damage. Preventive and biological control measures can be used to detect and control infestations at an early stage. In severe cases, chemical control may be necessary, but it should only be used as a last resort and with caution to prevent harm to beneficial insects and pollinators.
