Always practice crop rotation, especially for subsequent host crops. Once the infected leaves have been removed, spray a fungicide on the underside of the okra leaves in the afternoon. To control the spread of Cercospora leaf spot, remove and dispose of infected leaves. It is spread by wind, rain, and irrigation, as well as mechanical tool use. The most serious outbreaks occur after a period of rainy weather. As the disease progresses, the leaves become dry and brown.Ĭercospora survives in plant residue left from hosts such as beet, spinach, eggplant, and, of course, okra. This growth is present on the undersides of the leaves in the form of yellowing and brown spots. These spores adhere to the leaf surface and grow, becoming mycelia growth. Cercospora is a fungal infection wherein spores are carried by the wind from infected plants to other plants. The spots enlarge and coalesce rapidly and a white mass resembling talcum powder becomes evident on the upper surface of older leaves or other plant parts. Spots on okra leaves may also be the result of the pathogen Cercospora abelmoschi. These are not the only pathogens that may be responsible for okra with leaf spots, however. The best way to control okra with leaf spots caused by these organisms is to practice crop rotation and utilize a consistent fertilization program. No fungicides are available or required for these diseases. For the most part, none of these have been shown to cause any serious economic loss. Spots on okra leaves may be the result of several leaf spotting organisms, among these include Alternaria, Ascochyta, and Phyllosticta hibiscina. What is okra leaf spot and how can okra with leaf spots be managed? Read on to learn more. Even with centuries of cultivation, okra is still susceptible to pests and diseases. While mouthwash is an effective remedy for white mold, it can be harmful to new plant growth and burn leaves if used too often. Spread by wind, infected seeds, and water, they will affect okra flowers, foliage. Mix one part mouthwash with three parts water and apply to affected areas. Fungi, which cause this disease, may survive in the ground up to five years. Today, most commercially grown okra is produced in the southeastern United States. Ethanol-based mouthwash can be an effective treatment for white mold. The growth of okra seedlings exposed to salt stress (7 days) was inhibited significantly compared with those exposed to normal conditions (Fig. Heat loving okra has been cultivated for centuries, as far back as the thirteenth century where it was cultivated by the ancient Egyptians in the Nile basin. To explore whether exogenous melatonin pretreatment can alleviate salt stress of okra plants, melatonin (50 M or 100 M) was applied to okra seedlings and the phenotypic traits were observed.
