On May 31, the Chilean Agricultural and Livestock Service (SAG) ended the Official Control against the Psa in Kiwis, an action that declares that this disease is present in Chile.
"The repeal of the Psa official control doesn't change the actions we must perform at the field level. It remains a major pest, and farmers must continue carrying out their phytosanitary programs. In autumn and winter, they must conduct pruning sanitizing their tools before and after using them on each individual plant. Spring will continue to be critical for managing Flower Blight. From now on, during the harvest, the packing stations will have to eliminate vegetable remains. During the propagation the SAG will continue to control that good plant production practices are carried out in the nurseries,” stated Carlos Cruzat, president of the Chilean Kiwi Committee.
"We never thought that the disease could be eradicated, the objective of the controls was to prevent it from spreading as aggressively and disastrously as it did in Italy and New Zealand, delaying its advance and allowing producers to prepare to learn to live with it while preventing economic losses from being as disastrous as in other countries. We believe we achieved this goal in Chile, thanks to public-private work. That's why, after 10 years of work and the current coexistence with the disease, the SAG considers that the Psa is present in Chile, so the official control status was eliminated on May 31, 2020,” Cruzat stated.
“Now the industry must maintain the same work plans, phytosanitary programs, and care that the Psa Table has delivered, mainly through the Phytosanitary Program that is published twice a year with updates on control products and the management that must be incorporated into the premises," he added.
Psa was detected in the country 10 years ago. It is a bacterium that affects the productivity of kiwi plants, as it dries the plant's branches and dehydrates the fruit. In the long run, the plant ceases to be productive, thus it's very important that producers to continue carrying out prevention and control measures.
