Effects of crop residues in soil on phymatotrichum root rot of cotton

The effects of cropping pea or barley and the decomposition of their residues on Phymatotrichum root rot of cotton were studied for five years. Little or no changes occurred in pH, content of carbon or moisture in the soil, but there were significant increases in populations of competitive microflora. Best control was obtained in infested soil which was cropped to either pea or barley in winter or in soil which received the higher tonnage of Papago pea plants. Reduction in incidence of root rot may be attributed to premature germination of overwintering propagules making hyphae vulnerable to the chemicals of decomposition and to competition of microflora in the soil.

Effect of Soil Treatment, Soil Temperature, and Plant Age on Pythium Root Rot of Cotton

Effect of Soil Treatment, Soil Temperature, and Plant Age on Pythium Root Rot of Cotton

Interactions of actinomycetes with Macrophomina phaseoli (Maubl.) Ashby; the cause of root rot of cotton.

Macrophomina phaseoli, the cause of root rot of cotton, was inhibited byStreptomyces albus, S. griseus andS. noursei in agar culture.S. aureofaciens, S. flaveolus, S. rimosus, S. scabies andS. venezuelae were non-antagonistic. Only the antagonisticStreptomyces were found to reduceMacrophomina infection on cotton seedlings in soil without any deleterious effect on cotton growth.

Interactions of soil fungi with Macrophomina phaseoli (Maubl.) ashby, the cause of root rot of cotton

Interactions of 46 isolates of fungi with an isolate ofM. phaseoli from cotton, was studied in agar culture. They were grouped into 4 different types of reactions.T. viride was found to inhibit the growth ofM. phaseoli and grow over its colony. The hyphae ofT. viride were observed to coil around the hyphae ofM. phaseoli. A majority of the isolates tested had no effect on the growth ofM. phaseoli. M. phaseoli, however, was found to overgrow the test fungi.

Gibberella fujikuroi . [Descriptions of Fungi and Bacteria

Abstract A description is provided for Gibberella fujikuroi . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On several hosts of economic importance in the Gramineae ; also on a very wide range of hosts represented by the following families: Amarantaceae, Amaryllidaceae, Asclepiadaceae, Betulaceae, Bromeliaceae, Buxaceae, Caryophyllaceae, Coniferae, Cruciferae, Convolvulaceae, Cucurbitaceae, Euphorbiaceae, Iridaceae, Lauraceae, Leguminosae, Liliaceae, Linaceae, Malvaceae, Marantaceae, Moraceae, Musaceae, Palmae, Polemoniaceae, Rosaceae, Rubiaceae, Rutaceae, Scrophulariaceae, Solanaceae, Sterculiaceae, Tiliaceae (14: 708; 31: 515; 36: 501; 40: 89 and Herb. IMI). DISEASES: Causing seedling bright, food rot, stunting and hypertrophy of shoots ('bakanae') of rice; associated with seed rot, seedling blight, ear rot, root and stalk rot of maize and sorghum; stem rot and top rot ('pokkah boeng') of sugar-cane (also reported on sorghum); seedling blight, root rot and pink boll of cotton and seedling blight of wheat. Also recorded causing wilt in Crotalaria and decay to fruit of banana, pineapple and tomato. GEOGRAPHICAL DISTRIBUTION: Widespread in both humid and sub-humid temperate zones and extending into sub-topical and tropical zones in Africa, Asia, Australasia & Oceania, Europe, Central America & West Indies, and North & South America (CMI Map 102, Ed.3). TRANSMISSION: Both seed and soil-borne (13: 262) as well as by air-borne spores produced on over-wintered plant debris where the pathogen may retain its viability for over two years (12: 532).
