Sažetak
Chestnut forests are important resource and have significant economic, ecological and touristic role and are of biodiversity importance. Chestnut blight disease present in all chestnut stands is the most important problem for years. The research object of this work is to investigate integral methods for preservation the chestnut forest and to improve their health condition. To find out the best method for chestnut protection the investigation the health condition of chestnut forest and different research methods were performed in the field and laboratory. Experimental and control plots were established in two localities: in Petrinja and Hrvatska Kostajnica in Forest Administration Sisak in region with largest area of chestnut forest stands. On experimental plots the different methods of breeding and protection measures were carried out. In laboratory experiments the investigation of biological control of chestnut blight with antagonist fungi Trichoderma viride and Trichothecium roseum that are isolated from chestnut nuts were carried out. In experimental plot where mild thinning and cleaning were carried out the largest number of trees with superficial necroses and healing cancer were present. In control plot the trees with active cancer and dry trees were present the most. On chestnut leaves the fungi Microsphaera alphitoides and Mycospherella maculiformis were present from weak to strong infection degree. The health status of chestnut nuts showed that two-thirds were healthy and one- third was damaged with insects and fungi. The most present fungi on nut were Aspergillus spp., Ciboria batschiana, Fusarium sp., Penicillium spp., Phomopsis sp., Trichotechium roseum and Trichoderma viride. Detected insects on nut were Curculio sp. and Cydia sp. Schizophyllum commune, Stereum spp. and Trametes spp. decaying fungi were detected on chestnut trees. Biological control with antagonist fungi in laboratory experiment showed that fungus Trichoderma viride has grown over the Cryphonectria parasitica culture on 6th days and Trichtecium roseum on 29th day. The conclusion is that the most efficient and economical method of chestnut protection were mild thinning and cleaning with implementation of forest order. Laboratory experiment suggests the possibility of biological control with antagonist fungi which should be testing in natural condition in following research.
