Joseph and Jazmin compared organic sprays for managing disease in their young orchard, with the goal of discovering the best organic approach to care for their black walnuts.
- Disease and insect pressure was low on the young trees measured this year.
- While there was no statistical difference between the two treatments (neem oil vs copper and biological insecticide). They will continue measurements for a second year.
- The most significant indicator of fungal infection is early defoliation in the fall. Therefore, observations next year at the end of the season could strengthen their overall conclusions.
