Efficacy of different fungicidal chemistries (Topsin-M, Antracol, Captan, Benlate and Bavistin) was evaluated in vitro by the poison food technique against Colletotrichum gloeosporiodes. Anthracnose is a common fungus that is a problem for a wide range of plant types, including guava. Abstract. Results of investigation revealed that C. gloeosporioides was established as major causal organism. All the fungicides showed higher efficacy with the increase in the concentration levels. Similar observations have been reported by Malraja (1990) in spraying of Zn, Cu, Mn, Mg and Fe that reduced the incidence of disease of which Cu spray recorded least incidence of fruit rot in chilli. They found young immature guava fruits were free from infection while mature fruits were infected readily and this difference might be due to concentration of potassium ion at different developmental stages have been found. Commercial mango production in Hawai‘i (2005). As condições ótimas para a infecção do fruto foram sob temperatura de 26 e 27ºC, para 'Kumagai' e de 25 e 26ºC, para 'Pedro Sato', com 24 horas de molhamento. an important fruit of subtropical countries is affected by about 177 pathogens of which, 167 are fungal, 3 bacterial, 3 algal, 3 nematodes and one epiphyte. In another experiment tilt, rovral, Mn, B and Zn at 1000, 500 and 2000 ppm respectively were sprayed separately for three times at 15 days interval starting from early fruit stage. All rights reserved. To test whether on-orchard control of rots could be improved, some fungicides not currently registered for avocados were screened for inhibition of spore germination and mycelial growth in the laboratory. (1993). Pages 147-152 Published online: 26 … MOC: Mustard Oil Cake, SOC: Sesame Oil Cake, TSP: Triple Super Phosphate, MP: Muriate of Potash. Testing efficacy of fungicides against postharvest pathogens of avocado (Persea americana cv. One set of plants were kept for control treatment receiving no manures and or fertilizers. Guava (Psidium guajava Linn.) It sounds like anthracnose or black spot this diseases in the mangos will be a real problem this year because of all the wet weather. The organic manures, cowdung, MOC (mill) and their combinations improved the soil properties like texure, structure, aeration, water holding capacity etc. MOC (ghani) and cowdung+MOC (ghani) caused 3.2 and 2.8% respectively. … Survey of guava (Psidium guajava L.) orchards was conducted to assess the incidence and severity of fruit anthracnose of guava in Sheikhupura, Sargodha, Faisalabad, Hafizabad, Jhang and Chiniot districts of Punjab province. Anthracnose can survive on … Foliar spray: All the spray treatments significantly reduced fruit infection over control. Very slight infection occurred in NPK+ZnSO4+Gypsum, PK+ZnSO4, MOC (ghani) treated plants. First approach was done in two adjacent homestead garden and second approach was done in AIC fruit firm. Spraying were started from early fruit stage (fruit setting) and was continued for 3 sprays at an interval of 15 days. Manures and fertilizers were applied in the furrows and then thoroughly mixed with soil. Anthracnose. Remove and burn any infected plants in your guava plantation; Avoid too much water around your guava trees; Spray copper-based fungicides such as mancozeb 75% wp @2.5gm/liter of water and oxychloride 50% wp @4mg/liter; Preventions of Guava Anthracnose Disease OCCURRENCE OF GUAVA ANTHRACNOSE IN PUNJAB (PAKISTAN) AND ITS INTEGRATED MANAGEMENT Integration of various management practices has brought success in some crops (Raut, 1990; Singh et al., 1990; Adisa, 1985). Mango, Avacado, Lychee, Longan, - Duration: 7:46. and B.B. Foliar spray: No disease observed in tilt sprayed plants. For most of this article the. Table 1. The treatments with their doses are shown in Table 1. In the absence of NPK, plants become weak and at this condition gypsum would not be able to resist the disease singly (Ferdous, 1990). four fruits were anthracnose (Colletotrichum gloeosporioides), Fusarium rot (Fusarium sp. The pathogen has a wide host range and successfully invades mango, pear and apple fruits supported by Wahid (2001) and Peres et al. Annual research review (1988-1989). However, disease under natural condition is regulated by natural factors temperature, humidity and rainfall which vary from season to season and year to year. an important fruit of subtropical countries is affected by about 177 pathogens of which, 167 are fungal, 3 bacterial, 3 algal, 3 nematodes and one epiphyte.Wilt is the most important disease of guava.
