Type of Infestation
By feeding on the leaves and rolling them up to create a home for themselves, the sorghum leaf roller infests sorghum crops. 🍂🐛 Rolling or folding infestations are this kind. 🌿🏠
Scientific Name: Marasmia trapezalis
Most Affected States
The states of Maharashtra, Karnataka, Andhra Pradesh, Telangana, Tamil Nadu, and Madhya Pradesh are home to the sorghum leaf roller most frequently.
Symptoms of Sorghum Leaf Roller
The most common symptoms of infestation include:
- The larva of the sorghum leaf roller feeds on the leaves before rolling them into a shelter. 🍂🐛
- Longitudinal patches can be seen on infected leaves, especially close to the tips. 🌿🔍
- The leaves' tips shrivel up. 🍃💧
Control Measures
Consider an integrated management strategy to reduce the insect population if you are concerned about these sorghum leaf roller infestations. Here are some practical steps you can take to manage sorghum leaf rollers:
Cultural Measures
- To reduce the population of sorghum leaf rollers, crop rotation might be used. 🔄🌾
- Clear out and clean up any plant debris. 🧹🌱
- Don't use too many nitrogen-rich fertilizers. ⚖️🌿
- Reduce the sorghum plant's vulnerability to pests by maintaining optimum plant health through appropriate irrigation, fertilizer, and soil management techniques. 💧🌱🛢️
Mechanical Measures
- The simplest technique to prevent leaf roller damage is to manually remove and destroy rolled leaves.
Biological Control
- To reduce the number of sorghum leaf rollers, release Trichogramma chilonis, an egg parasitoid, in sorghum fields. 🐞🌾
- The biological pesticide Ecotin, which is based on neem and contains azadirachtin, can be used successfully to manage leaf rollers on sorghum plants. 🌿🛡️
- The dosage ranges from 0.4 to 0.7ml per liter of water. 💧🌱
- Bacillus thuringiensis, which generates a protein that stops the insect's digestive system and kills it, is present in Katyayani Organic Larvicide. 10ml per liter of water is the suggested dosage. 🦠🌿
Chemical Measures
Commercial insecticides can be used to manage the sorghum leaf roller population if the infestation is bad enough. Following are some popular pesticides for preventing leaf rollers:
As a result, if not adequately controlled, sorghum leaf rollers can seriously harm sorghum harvests. 🌾🚫 Following the integrated tactics listed above will help you stop the sorghum leaf roller from rolling over your crops. 🌱🛡️
