 Objectives

Spil solarization for the control of Avocado dry root rot

 Study of the biology of the pathogens responsible for the main crop diseases in Crete.

 Study of the rhizosphere antagonistic microflora.

 Development of methods, techniques and means on integrated or biological control of diseases, to reduce the impacts of the use of chemicals on the agroecosystem and the public health.

 Study on the effectiveness of new active substances with fungicide and bactericide action.

 Use of mild fungicides for the control of plant diseases.

 Results

 It has been developed and it is now widely applied the physico-biological method of soil solarization for the control of pests, pathogens and weeds and the improvement of soil fertility.

 The total soil mycoflora of the greenhouse areas at the prefecture of Chania has been analyzed. There were isolated 10 beneficial species which could be used on the preparation of biological products or artificial suppressive soils for the control of soil pathogens.

 Utilizing the phenomenon of allelopathy, there have been developed methods of using vegetative essential oils in practice for the control of Botrytis on tomato and Ascosphaerosis on bees.

 It has been studied the possibility to control crop diseases by the use of biological products and soft fungicides, such as sulfur with Thiobacillus, parafinic oils, sodium bicarbonate and phosphonate compounds.

Control of Verticillium dahliae on jojoba

 It has assisted towards the development of an integrated program for the control of Botrytis, based on the monitoring of the pathogen resistance level and the use of specific plastic material for the roof of the greenhouse.

 It has contributed, through relevant studies, to the production of a specific plastic material with high impenetrability in methyl bromide.

 It has supported the approval of 15 new fungicides through experiments for the effectiveness of new active substances.

 Biological and chemical methods have been studied and developed for the control of new diseases observed on citrus trees and kiwifruit plants (citrus dry root rot, Alternaria of kiwifruit plant).

 It provides technical support to approximately 500 growers every year, for the control of the phytopathological problems of their crops.

 Is studied the growth of techniques and means as alternative of the methyl bromide in the control of soil pathogens of greenhouse vegetables.

 Efforts have been made for the development of artificial suppressive soils with selective indigenous antagonists for the control of soilborne diseases in various crops.

 Towards the direction of reducing fungicide and especially copper doses, the use of spraying solution ionized with cooper ions was studied.

 It is studied the possibility to control soilborne diseases with the use of ozone diluted in the irrigation water alone or in combination with antagonistic fungi.

 It is studied the effectiveness of the plant defense system stimulator harpin Ea for the control of soilborne as well as upper part diseases.
