AbstractInvestigation into the control of Roselinia neeatrix (Hart.):Plant susceptibility and chemical treatment. When artificially inoculatyed with Rosellmia necatrix (Hartig) Berlese, igneous species showed important differences in suseeptibility to this fungus. Some of them appeared resistant.Several herbaeous species were also infected and can be regarded as potential source of inoculum in nature.Chemical control of Rosellinta was investigated. The main results indicate the best way to use benzimidazoles

摘要:

AbstractIn the infection cycle of Armillaria spore dispersal is followed by colonization of stumps, which is not uncommon on the time‐scale of plantation forestry. After a period of exploitation, further suitable woody tissues nearby may be colonized by means of rhizomorphs or direct mycelial transfer. The cycle is illustrated by four species present in southern England, which vary in pathogenicity, capacity to invade tissues deelining in resistance, and ability to form rhizomorphs. Various host responses, such as production of oleoresin by conifers and secondary meristematic activity, are briefly discusse

摘要:

AbstractInvestigation into specialisation of Armillaria obscura and Armillaria mellea. Two isolates ofA. melleaproved more aggressive than two ofA. obscuraas regards vine, peach and northern oak. Inversely, the isolates of obscure were more aggressive than those of mellea towards Norway spruce and Maritune pine.On the other hand no type of specialisation was found when investigating the saprophytic phase: oak wood is better than pine wood as regards rhizomorph production forA. observeas well asA. mellea.

摘要:

AbstractArmillaria obscura in the forest exosystem of Cerdagne. The “Rings” of Armillaria obseuja are surveyed in the pinus mcinala forsest of Cerdagne (french eastern Pyrenes). The fungus can be considered as a natural rejuvenation agent of forest stands. The determinism of the beginning of attacks is not well elueidated. The plants successions in destroyed stands are descri

摘要:

AbstractA general panorama is given, especially for Armillaria and Heterobasidion, on specific difficulties to find effective control methods. Lack of knowledge remains large and more reserch in needed to achieve a right base to better understand what is possible in the field of resistance breeding and biologice control.

摘要:

AbstractNew method of direct control of Rigidoporus lignosus, causing agent of white root rot of Hevea. A new method of direct control of Hevea whith root disease caused by Rigidoporus lignosts (Kl.) Imaz is being used in many countries in Africa; after detection and marking diseased trees and trees in direct contact, the treatment consists of pouring 21 of 0.5% calixin cmulsion into the cuvette 2 times every 6 months. This method which has been used in field trials for 3 years, seems to give encouraging results. and has confirmed the efficiency of Calisin for direct control of the white root disease.

摘要:

AbstractIs it possible to control diseases of woody plants by means of their mycorrhizae?The role of mycorrhizaae as biological detcrrents to soil borne diseases are reviewed from the literature and author's experiments in relation with nature of host plant, of mycorrlizal fungi, soils conditions. Possible mechanisms are discussed. Protective ability of some mycorrhizae appears as a potential, the expression of which depends of environmental factors, Mycorrhizae could be a biological mean to control soil borne diseases since we have a better ecological knowledge of their relationship with biotic components in the soil.

AbstractResearch for a method of biological control against ink disease by using mycorrhizal symbiosis. The utilisation of mycorthizal symbiosis against a swect chestunut pathogen scvems to be the only type of biological control possible. The antagonism of mycorrhizal or peritrophie fungi as regands Phytoph thoni cinumuni was studied in the laboratory. The resistance of plants moculucd with such fngi was tested in grecnhouse trials and by planting in plox of contanimared soil.
