Abstract

Seventeen wood decaying fungi occurring on teak in Madhya Pradesh are reported. Eleven of these fungi are reported as new records on teak and six are being reported as new on teak from Madhya Pradesh. There are two ischolar_main rot fungi on living trees of teak, Aurificarea shoreae and Ganoderma lucidum.

Abstract

Boswellia serrata wood is economically important for various purposes, but is non-resistant to fungal decay. In all, 14 wood decay fungi were collected on B. serrata stored wood, 12 of them being recorded for the first time from Madhya Pradesh. One brown rot fungus was also recorded.

Abstract

The cellulolytic activity of some wood decaying fungi using filter paper cellulose was screened. All the species tested decomposed cellulose. Oxyporus ravidus and Funalia leonina exhibited maximum cellulolytic activity. While Pyrofomes tricolor was slow decomposer. The decomposition rate varied considerably with all the tested fungi. It was found that the initial pH value of the medium changed considerably after incubation period.

Abstract

Ganoderma lucidum is used in different hosts viz. Albizia lebbek , Boswellia serrata , Delonix regia , Populus deltoides , Leucaena leucocephala and Lannea coromandelica for artifical cultivation in control condition. The better performance was observed in Delonix regia for the production of G.lucidum.

Abstract

The occurrence and distribution of 81 wood decaying fungi on different hosts in forest wood depots of Chhattisgarh is reported. The study area is confined to nine wood depots and each wood depot, depending on area occupied, is divided into five sectors. The maximum number of wood decaying fungi reported in Gariyabandh wood depot and minimum number of wood decaying fungi reported in Kota and Dhamtari. Out of 79 specimens, 3 species including Schizophyllum commune Fr., Trametescingulata Berk. and Flavodonflavus (Klot.) Ryvarden, were common to all nine wood depots areas and show their occurrence and frequency 100%.

Abstract

Study was made to test the efficacy of five Trichoderma species (biocontrol agents) and two fungicides, on suppression of Ganoderma lucidum Karst. invasion in ischolar_main block of Albizia procera Benth., tree in two type of media in-vitro. The fungicides used were Bavistin(0.2%) and Bordeaux mixture (5:5:50) while the biocontrol agents were Trichoderma pseudokoningii, T. longibrachiatum, T.atroviride. T.polysporum and an unidentified Trichoderma sp. isolated from A.procera living ischolar_main surface. The test fungus, Ganoderma lucidum was isolated from A.procera. After 8 weeks of incubation (27±2°C), Bavistin and Bordeaux mixture were found equally effective in minimizing weight losses in different combination of biocontrol agent. The best treatment combination was Bordeaux mixture + T.polysporum in sand soil medium.

Abstract

Damage caused by heart-rot in teak trees in natural forest has been estimated in Madhya Pradesh (Central India) where 38% to 88% trees were found affected by heart-rot. Loss assessment made in stored teak logs in the depots revealed that about 39% logs were having heart-rot entailing an average loss of about 11% in wood volume. This loss in wood volume has been calculated to the tune of nearly Rs. 200 million annually on the basis of market value of teak.

Abstract

Khair mortality was recorded in two central Indian states, Madhya Pradesh and Maharashtra. Mortality was observed in 9-20 years old plantations upto 93 per cent in both states due to ischolar_main rot disease caused by a fungus, Ganoderma lucidum. In Madhya Pradesh, the worst affected areas are Palpur (Sheopur) and Ghuniya beet (Indore) having maximum 93% and 40% mortality respectively. In Maharashtra, Hiwari range of Yavatmal was found as the most affected site having up to 60% mortality due to this disease. Fusarium sp. also causes 3% mortality in one year old plantation at Akoli beet, Pandherkawda (MS). Total 17 fungal species were found associated with different stages of khair mortality which include 6 fungi, namely Hapalopilus nidulans, Lenzites pisolotii, Monodictys castaneae, Resinicium bicolor, Rigidoporus vinctus and Trametes hirusita recorded for the first time from central India.
