![]() ![]() Harvested roots can be processed into various goods, including flour, chips, and starch, greatly enhancing global food security and generating cash. Key pests include the green mite and the cassava mealybug, which must be managed properly to prevent Disease and infestation. Cassava is grown from stem cuttings and is normally harvested between 8 and 18 months following germination. It flourishes on sandy loam soil that is well-drained and has a pH range of 5.5 to 6.5. Manihot esculenta, also called cassava, is an important crop grown worldwide, particularly in tropical areas. Major Pests and Diseases of Cassava What is Cassava Farming? In this expert overview, we examine the main pests and diseases affecting cassava, looking at their traits, effects, and potential countermeasures. It is essential to comprehend these foes to develop successful solutions for preserving cassava output and ensuring sustainable agricultural practices. Significant risks come from pests like the cassava mealybug and illnesses like cassava mosaic disease. In many tropical regions, these issues put food security in jeopardy. ![]() Integrated Pest and Disease Management for Cassava Cultivationĭespite being a crucial crop for the world, cassava (Manihot esculenta) is threatened by several serious pests and illnesses.Cassava Fusarium Wilt: Understanding and Controlling Spread.Cassava Scale Insects: Impact and Management Practices.Cassava Bacterial Wilt: Diagnosis and Control Methods.Cassava Leaf Miner: Identification and Integrated Pest Management.Cassava Root Knot Nematodes: Effective Control Approaches.Cassava Stem Borers: Prevention and Management Techniques.Cassava Rust Disease: Symptoms and Control Measures.Cassava Witches’ Broom Disease: Control Strategies.Cassava Red Spider Mite: Prevention and Control Measures.Cassava Whitefly: Impact and Integrated Pest Management.Cassava Root Rot: Diagnosis and Treatment Options.Cassava Anthracnose: Effective Control Methods.Cassava Mosaic Disease: Understanding and Controlling Spread.Cassava Brown Streak Disease: Detection and Management.Cassava Bacterial Blight: Prevention and Control.Cassava Green Mite: Symptoms and Management Strategies.Cassava Mealybug: Identification and Control Measures.Phone Dr Alina Mofokeng on 0, or email her at. This will allow you to take appropriate action in time to prevent yield loss. It is crucial, however, to monitor the leaf canopy frequently during pod development for early signs of blight symptoms. The disease can be managed in several ways: cultural practices, intercropping cowpea with maize or cassava, planting disease-free seed, and timely application of registered chemicals.Ĭowpea genotypes that are resistant to bacterial blight show good potential. The pathogen can survive in the soil for 260 days at 10☌ and 100 days at 40☌.įarmers who plant their own seed from the previous season could suffer a 100% crop loss if the seed is already infected and cool, wet weather conditions prevail. The bacteria can remain viable for nearly 400 days in infected seed and debris at temperatures of 5☌ to 10☌, and for 250 days at temperatures between 10☌ and 40☌. In a severe infestation, pod development is poor and most of the seeds are shrivelled and unable to germinate. Infected seeds are discoloured and shrivelled. The pathogen also invades the stem, causing cracking with brown stripes, and the pods, where they manifest as dark green, water-soaked areas. They often expand, join up and develop into large necrotic lesions. Initial symptoms are tiny, water-soaked dots under the leaf. These vary from pinpoint size to more than 1,25cm in diameter, with a yellow halo. Seed and crop residue are the main source of infection, but it is also spread by insects and wind-driven rain. This aggressive pathogen is carried on the seeds and can survive in soil, crop residue, and seed, as well as on alternative hosts such as lablab bean, common bean and sunn hemp.
