Abstract
Citrus Green mold disease
caused by Penicillium digitatum Sacc
is the most important postharvest disease of lemon in Tucumán. The use of lemon
essential oil (LEO) is a promissory alternative to control this mould. The
objective of this work was to evaluate LEO effectiveness at two doses to control
citrus Green mold in lemon fruit. Mature fruits were inoculated using a punch
previously dipped in a suspension of 1x106 spore/ml of a strain
isolated from packing house, and incubated in chamber at 22°C. Subsequently the
fruits were dipped during 30 seconds with the following treatments: T1 Control
water, T2 Lemon essential oil 0.5%, T3 Lemon essential oil 1%. The experimental
unit was composed by 10 fruits. A DCA design with tree replicates (30 fruits
per treatment) was used. After 10 days stored at 6°C the sporulation grade (SG)
was evaluated using a 5 grade scale (0-4) at 10 intervals. Disease Progress
Area Curve (DAPAC) was constructed and ANOVA was used to compare mean values
with the Fisher test (5%). Both treatments with LEO were different (DAPAC 56.0;p=0.0012) to control, the best treatment was T3 (28.7) presenting no
difference with T2 (36.4) Although more studies should be conducted to further
characterize LEO in comparison with commercial fungicides, this result
constitute a promissory alternative to control citrus green mould caused by P. digitatum.
