DISEASE AND PESTS OF OLIVE (OLEA L.) PLANT

Abstract

The research paper mentions olive leaf spot [Spilocaea oleagina (Cast.) Hughes, Syn: Cycloconium oleaginum Cast], as well as olive moth (Prays olea Bern.), olive psyllid (Euphlyllura olivina Costa.) pests that are widespread in the olive plant and their control measures. The experiments were carried out on the territory of the Absheron Experimental Station of the Scientific Research
Institute of Fruit and Tea Growing on Azerbaijani olive, Pikvales, Agbaba, Jigrina varieties. As a result, it was determined that although olive leaf spot disease infection was observed in all 4 varieties, the degree of infection was different according to the varieties. Thus, against the disease, the Azerbaijani olive variety is the most unstable variety, with 23.5% in 4-point infection, and the Jigrina variety (12%) is more resistant. 16.5% infection was observed in Agbaba variety and 15% in Pikvales variety. The degree of pest infestation of the varieties was also evaluated with a point and a resistant variety was selected. It was determined that Jigrina variety (1 point) is more resistant to pests. The degree of durability of other varieties was relatively low and was evaluated with 2-3 points. From this point of view, it is more appropriate to cultivate the Jigrina variety more widely and use on the farm. Chemical and agrotechnical measures against diseases and pests found in varieties have been developed.
