AMALGEROL shows high anti-sunburn effectiveness in 4000 evaluated apples

Large-scale field experiment following scientific standards to test the efficacy of AMALGEROL in preventing sunscald (sunburn) on apples. Sunburns in Southern Russia look like yellowish spots, solid concave spots, or non-concave soft spots. The presence of sunburns was evaluated as well as the extend (fruit surface burned up to 5 %, 6 - 10 %, 11 - 20 %). 

0,9 ha of the intensive apple orchard were sprayed with AMALGEROL once (2 l/ha on July 31st). 0,1 ha was left untreated. Four replicates of each option were tested. Ten model trees with a typical yield were sampled for each replicate. A total of 100 fruits were inspected on each tree, altogether 1000 fruits in each replicate, 4000 fruits in each option.

Sunburn was evaluated 4 times after the AMALGEROL treatment (each 10 days, see chart below). In this trial, sunscald caused a yield loss of 2,5 t/ha compared to the trees treated with AMALGEROL against the sunburn.

Therefore, AMALGEROL is highly effective and economically worthwhile especially for late ripening apple varieties that are particularly prone to sunscald.
