The paper is written on the basis of research conducted on walnut tree in 2017–2019 in the Ismayilli, Gabala, Zagatala and Khachmaz regions of Azerbaijan. As a result of research, the following pests were recorded: aphids Panaphis juglandis and Chromaphis juglandicola (Aphididae); beetle – Sarrothripus musculana Ersch. (Flatidae) Stephanitis pyri (Tingidae); butterfly – Hyphantria cunea (Lepidoptera, Arctiida), fly – Polyodaspis ruficornis Mcq. (Diptera, Chloropidae).

Non Destructive

Nitrogen (N) deficiency reduced biomass and altered N allocation within large walnut tree canopies (Juglans regia L. cv Serr). N-fertilized control trees contained 2.5 times more N in current year spurs, leaves and fruit than did those of N-deficient trees. The N content and biomass allocated to kernels was reduced in N-deficient canopies to a greater extent than was al location to current year shoots and foliage. N removal in abscised leaves and fruit was 3 times greater in canopies of fertilized trees than in N-deficient trees.A non-destructive method is described to calculate total spur, leaflet and fruit numbers. Calculations were based on ratios of fruit counts on selected scaffold limbs to total fruit number per tree. Dry weight and N content of representative spurs, leaflets and fruit permitted estimation of whole canopy biomass and N content in these organs. N contained in current year spurs and the N lost from the tree in fruit and leaf litter were calculated for both N-fertilized control and N-deficient trees.

Protection Strategies

Many walnut orchards were inundated by flooding from the Feather and Stanislaus Rivers in winter and spring 2017 and developed bleeding cankers in trunk, root, and crown tissues exposed to the water. Orchard surveys and diagnostic isolations associated Phytophthora pini, P. chlamydospora, and P. gonapodyides with the cankers in 2017. Pathogenicity of P. pini was confirmed in seedlings and excised shoots of Juglans regia, but the other species caused negligible amounts of disease. Feather River and associated flood waters were assayed using culture-independent sequencing of rRNA gene amplicons and pear baiting methods; 14 species of Phytophthora were detected, including P. chlamydospora and P. gonapodyides, but not P. pini. Severe and prolonged walnut orchard flooding from rivers, such as occurred in 2017, places diverse mixtures of Phytophthora species from multiple sources into close, infective proximity with susceptible walnut tree scions. Systemic chemical or genetic protection strategies may be valuable for orchards subject to such flooding.
