D. Weed Management I. both Pyriform and Round cultivars across different regions in central and southern Punjab were found infected with wilt Further characterization and screening of elite guava strains for tolerance against wilt disease is in progress. Although various pathogens are en-countered to cause guava wilt, two species of Fusarium In vitro selection is a feasible method for developing wilt resistant or tolerant genotypes of guava.Unlike other crops, this approach has not been well established for guava. Abstract. In West Bengal, the disease reduced the yield by 80% i.e., from 113.5 q ha-1 in healthy plantations to about 18.16-22.7 q ha-1 in affected orchards (Chattopadhyay and Sengupta, 1955). Wilt is the most important disease of guava. Wilt: The exact cause of the disease is still not fully understood but the pathogens, viz. Biological control with Aspergillus niger ANI7 (Pusa Mrida), Penicillium citrinuni, Trichoderma sp. Further characterization and screening of elite guava strains for tolerance against wilt disease is in progress. Such studies will lead towards identification of guava strains tolerant to GWD for future breeding and biotechnology applications. The plants Round, Large Gola and disease. However, P. citrinum isolate showed less control. INTRODUCTION Guava (Psidium guajava L.) of Myrtaceae family is the sixth most cultivated fruit in India. November, … pre and post harvest rots of fruits. Guava (Psidium guajava L.) is an important fruit crop of subtropical countries and cultivated extensively throughout India, it is grown almost in all the states. serious limitation of guava cultivation is wilt disease. PDF … This paper briefly discussed the situation of guava cultivars in the major guava growing countries of the world. This pattern of genetic variability in the isolate was also supported by the analysis of the similarity indices and UPGMA dendrogram. Corn meal medium was found best for multiplication of guava wilt antagonists, Trichoderma harzianum, and Aspergillus niger. Interestingly, both the isolates of F. chlamydosporm were pathogenic but the two isolates of F. moniliforme and the non-pathogenic isolate of F. oxysporum could not cause wilt in guava plants. Out of 14, only 8 isolates of F. oxysporum f. sp.

Among the botanicals, Arjuna bark (Arjun) with ethanol, Papaya with ethanol, Neem leaf with water, Neem leaf with ethanol, Neem bark with ethanol, Neem oil, Black cumin with water, Black cumin (Kalojira) Oil, Swallow Wort (Akanda) with water, Henna (Mehedi) with water, Henna (Mehedi) with ethanol, Ivy Gourd (Telakucha) with water, Alamonda leaf with water, Periwinkle (Nayant ara) with ethanol, Malabar Nut (Bashak) with ethanol, Drumstick (Shajina) with ethanol, Garlic with ethanol and Betel leaf with ethanol significantly inhibited the radial mycelial growth of Fusarium oxysporum with higher concentration at different DAI. All rights reserved. Guava is grown almost in all the states of India. Fruit fly: Fruit fly is serious pest of guava fruits during monsoon. significantly for the subject. Co-cultivation with . Bihar has the largest area (24.7 thousand ha.) Misra on Dec 22, 2016, Conference (East Zone), Indian Society of Mycology. Guavas. Similar results were obtained when 10 randomly amplified polymorphic DNA markers (OPA I-OPA 10) tested in the genome of Fusarium solani and grouped on basis of obtained allelic data. Wilt, associated with the fungi Fusarium solani and Macrophomina phaseoli, brings about gradual decline and death of undernourished 1-to 5-year-old guava trees in West Bengal. Its management through chemicals being ineffective and moreover not possible due to huge soil mass, Planning for utilizing the knowledge in some organization, Guava (Psidium guajava Linn.) and Maharastra (14.8 thousand ha.). I feel humble and privileged to deliver this presidential lecture for the year 2015. Guava wilt is a serious problem in its cultivation. Besides, about 42% of 270 ha from the area that have cultivate guava in Malaysia have affected by this disease. Symptoms Wilt is a pernicious disease and a curse to guava industry. and 300 acres of guava orchards in Punjab and Haryana respectively were uprooted during 1978-81 (Jhooty et al., 1984). University of KwaZulu-Natal . Keywords: Antagonist, bio-efficacy, guava, wilt disease. Guava Wilt iv. The guava wilt fungus was also compared with Glio-cladium (Penicillium) vermoesenii (Biourge) Thom (Schoeman et al 1997) and Clonostachys (as "Gliocla-dium roseum Bainier series") (Thom 1930). Wilt is the most destructive disease for guava plant in India and losses due to this disease are [15, 13, 14]. Wilt: The symptoms of the disease appear on infected trees many months after their roots are Fully grown up trees bearing full crop start wilting and drying sudden ly in a period of few years, the orchard is wiped out. On hatching, the maggots enter into the fruit and in most of the cases fruit drop occurs. Several pathogenic fungi, nematodes and bacteria were found associated with the wilted trees of guava around the world; however, Fusarium spp. Special Characteristics . Pyriform * Not as per the appmved usage under Insecticide Act, 1968 . In severe cases the entire tree may die. Several pathogens are reported for the cause of the disease. Data in Table (1) indicate that disease incidence and severity of root rot and wilt complex differed in the tested fruit crops in different inspected locations in the New Valley Governorate. Guava (Psidium guajava Linn.) Canker 4-5 4. Wilt is a serious disease of guava crop in India. psidii. Discipline of Plant Pathology . Guava Wilt iv. PEST: Guava Root-Knot Nematode, (Meloidogyne enterolobii) BASIC PROFILE: M. enterolobii . According to Pandy and Dwivedi (1985), about 30% of the losses caused by wilt disease in India. 1. This study was conducted on cultural and physiological (temperature and pH) characters. Das Gupta and Rai (1947) recorded the disease in the severe form the orchards of Lucknow for the first time India. psidii, bactenal isolate isolated from R. communis (LLBP 2) showed greater inhibition capacity (33.11-40.27% inhibition) agaist the five selected isolates of F. orysporum f. sp. Most of the elite strains in both Pyriform and Round cultivars across different regions in central and southern Punjab were found infected with wilt disease. under guava cultivation followed by Uttar Pradesh (18.5 thousand ha.) South Africa . You can download the paper by clicking the button above. Bihar has the largest area (24.7 thousand ha.) psidii caused wilt in both the replicates and five showed 75% wilt in only in one plant. During the three years tested, guava wilt disease was low in incidence (5%) while the two bioagents completely suppressed wilt. Several pathogenic fungi, nematodes and bacteria were found associated with the wilted trees of guava around area.
