Effectiveness of Low Copper-Containing Chemicals against Olive Leaf Spot Disease Caused by Venturia oleaginea
نویسندگان
چکیده
The high level of copper (Cu) accumulation in the soil, risk surface water contamination, and potential public health problems due to Cu entering food chain have raised concerns on use compounds agriculture, including olive growing. As a consequence, there is worldwide regulatory pressure agricultural systems limit compounds. Hence, field trial was carried out evaluate effectiveness low containing chemicals control leaf spot (OLS) disease caused by Venturia oleaginea. conducted 2021 an (cv. Nabali Baladi) grove Palestine. Copper complexed with lignosulphonate gluconate (Disper Max®) self-defense inducer Disper Broton GS® were evaluated compared dodine traditionally frequently used hydroxide. In addition, untreated trees as control. Treatments made March, July, August. March 2021, leaves grown 2020 present 100% infected. V. oleaginea infections defoliation treated varying degrees intensity: Control had most defoliation, followed hydroxide Max®, whereas and, particular, least. All treatments reduced symptomatic but their efficacy varied significantly: least effective, Max® intermediate, mainly, effective. Overall, results are promising since able significantly reduce OLS damage amount for treatments.
