The pathogen can affect foliage, young shoots, inflorescences and fruit of guava. The severity of the infection depends on both the causative agent and the infected species and can range from mere unsightliness to death. Agaves are also often afflicted, most often in the fall when the weather is wet. The experiments consist of 6 guava fruit intact to the twigs inoculated with sterile PDA agar discs and incubated as described above. The pathogen can affect foliage, young shoots, inflorescences and fruit of guava. Out of 12 guava trees examined 10 of them were found associated with severe anthracnose infection and on most of the trees over 40% of the fruit produced were infected.

Infected plants develop dark, water soaked lesions on stems, leaves or fruit. Pathogenicity test: Six freshly harvested guava fruit intact to the twigs were surface sterilized by swabbing with 70% alcohol and placed in the conical flask containing sterile water when the distal end of the twigs immersed in water. This disease causes dieback and premature falling of guava leaves and … Find more gardening information on Gardening Know How: Keep up to date with all that's happening in and around the garden.

Causal organism – Colletotrichum gloeosporioides. Eighty percent of the guava plants were found infected with anthracnose disease and over 40% of the fruit produced on those trees were severely infected. Glœsporium psidii was isolated from die-back of guava trees. fruits in three major markets in Ibadan, Nigeria. ... 1. also gathered that those guava plants with no symptoms deterioration by the fungal pathogen. Be sure to completely destroy any infected parts or complete plants so they do not infect other areas. Anthracnose caused by G psidii is also common at Lucknow but in winter crop symptoms do not develop well as compared to rainy season crop (Misra and Prakash, 1986). Guava fruit showing symptoms of infection and the non-infected ones were collected from home gardens in Apata, Ojo and Moniya all within Ibadan metropolis. Nutrient composition: Three guava fruit each from Apata and Moniya were used for the analysis; at 3 days interval for 9 days along with 10 freshly picked fruits. Pestalotia psidii and Macrophomina sp. The non-infected guava fruit was found to be significantly higher than the anthracnose infected guava fruit in the percentage carbohydrates, crude fibre, ash, fat, protein, Ca, Fe and P. These differences may be due to deterioration caused by the fungus, since the fungus requires some essential nutrients for growth and survival[3,16]. 19.2 Causal organism Anthracnose of guava fruit is caused by Gloeosporium psidii Declacr = Colletotrichum sp. Symptoms of grayish, circular, sunken spots approximately 5 cm long were observed only on the surface of green unripe fruits. Seeds from the infected fruits harboured the pathogen. DIE BACK PHASE • The plant begins to die backwards form the top of a branch while the young shoots, leaves and fruits are readily affected. The surface-sterilized fruits showing symptoms of canker were then sliced into 2 mm2 pieces, then plated on sterile Potato Dextrose Agar (PDA) in petri dishes and incubated for six days under alternating 12 h light and dark periods at 26°C. While the other fungal isolates includes Fusarium sp. Increase in moisture content of the infected guava fruit may be due to increased exposure of damaged tissues to moisture absorption as a result of deterioration by the fungal pathogen. In Puerto Rico, up to 50% of the guava crop (mainly from wild trees) was reportedly ruined by the uncontrollable fungus, Glomerella cingulata, which mummifies and blackens immature fruits and rots mature fruits[2]. On leaves, guava anthracnose usually appears as It also attacks developing shoots and expanding leaves.

Samson[1] reported that the crude protein, carbohydrates, crude fat content of the guava fruits were 7, 11 and 17.1%, respectively which is in consonance with the report of this finding. The non-infected guava fruit was significantly higher than the anthracnose infected guava fruit in the percentage carbohydrates, crude fibre, ash, fat, protein, Ca, Fe and P (Table 1 ). The spots often enlarge up to 1-2 cm in diameter and their central portion becomes dark black due to the presence of black acervuli. You’ll notice small, circular or irregularly shaped dark or brown dead spots on the leaves, dead leaf margins and tips, and large dead blotches along the leaf veins or in-between the veins. 6.3: Symptom of canker on fruit.
