21 Niger Seed Cercospora leaf spot Disease Cercospora guizoticola Disease appears as small straw to brown coloured spots with grey centre on the leaves, spots may coalesce causing defoliation. Later the spots increase in number and size and cover the entire lamina and the leaves start dropping off. Elongated dark brown spotsare produced on the stem. The capsules are also affected. Seed treatment with two foliar sprays of Carbendazim 50WP (0.2%) + Mancozeb (0.1%) can manage the disease. NULL 8,629
22 Niger Seed Alternaria leaf spot/blight Disease Alternaria sp. The disease appears as concentric rings on the leaves, which turns brown with grey centre later on. As the disease advances, the spots become oval or circular and irregular in shape. The infected leaves become dry and lead to the defoliation. Further it, spreads to other plant parts and results in to premature drying of the plant. Use of resistant varieties. NULL 8,629
23 Niger Seed Curvularia leaf spot Disease Curvularia lunata Small circular to irregular brown to reddish brown spots which later coalesce to form larger spots. The leaf turn yellow dries and defoliates. NULL NULL 8,629
24 Niger Seed Powdery mildew Disease Sphaerotheca spp. The diseased leaves turn yellow and drop off. The seed formed on diseased plants are small and shriveled. The disease can be managed by burning the infected plant parts after the harvesting of the crop. The disease can also be effectively controlled by spraying with sulfex. NULL 8,629
25 Niger Seed Rust Disease Puccinia guizotiae Brown pustules diameter appear on the leaves. The lesions consist of densely aggregated brown telio. The uredosori are formed on the lower leaf surface and the corresponding upper surface becomes chlorotic. Later teliospores are formed. The disease can be managed by spraying crop with Dithane M- 45 as the disease starts appearing. NULL 8,629
26 Niger Seed Bacterial leaf spot Disease Xanthomonas campestris pv. guizotiae Small brownish spots are formed on leaves which are surrounded by yellow halo. The disease can be managed by spraying the crop with Blitox-50. NULL 8,629
27 Niger Seed Weed dodder (Cuscuta hyalina) Weed NULL The plants remain stunted, pale yellow and bear a very small number of flowers and fruits. The Cuscuta seeds can be removed by sieving before sowing. Removal of cuscuta infected Niger seed at the early crop growth. NULL 8,629
28 Chinese Spinach Stemrot Disease Choanephora cucurbitarum NULL A wider spacing may reduce the rate of infection. NULL 8,631
29 Chinese Spinach Damping-off Disease Pythium and Rhizoctonia NULL It is controlled by good drainage. Over-dense sowing should be avoided. NULL 8,631
30 Chinese Spinach White rust Disease Albugo bliti NULL NULL NULL 8,631
31 Chinese Spinach Leaf and stem blight Disease Phomopsis amaranthophila NULL NULL NULL 8,631
32 Chinese Spinach Caterpillars (Hymenia recurvalis, Spodoptera litura, Heliothis armigera) Pest NULL NULL NULL NULL 8,631
33 Chinese Spinach Larvae of the stem borer (Lixus truncatulus) Pest NULL NULL NULL NULL 8,631
34 Jicama Yam Bean Mosaic virus Disease Aphids (Aphis spp.) or mealy bugs (Ferrisia virgata) and possibly by seed. It results in smaller-sized tubers (yield reductions of 20-30%), discoloured leaves and brittle stems. NULL NULL 8,632
35 Jicama Yam Bean Witches' broom disease Disease Contamination originating in the indigenous flora. NULL NULL NULL 8,632
36 Teff Leaf rust Disease Uromyces eragrostidis NULL Fungicides that control these two diseases have been identified at experimental level, although there are no known cases of field applications. NULL 8,628
37 Jicama Yam Bean Rose beetle (Adoretus versutus) Pest NULL NULL NULL NULL 8,632
38 Teff Head smudge Disease Helminthosporium miyakei NULL Fungicides that control these two diseases have been identified at experimental level, although there are no known cases of field applications. NULL 8,628
39 Jicama Yam Bean Bruchids (Bruchus spp.) Pest NULL NULL NULL NULL 8,632
40 Teff Damping off Disease Drechslera spp. and Epicoccum nigrum NULL Fungicides that control these two diseases have been identified at experimental level, although there are no known cases of field applications. NULL 8,628
