Abstract:
In recent decades, positive
changes have been occurred on the fruit
crops protection, because of new synthetic
or natural substances, more effective and
less toxic. In 2011, at Fruit Growing
Research and Development Station Iaşi,
Romania, was tested a phitosanitary
program that aimed especially to control the
main pest of apple, being introduced the
next generation of plant protection products,
such as: Coragen, Proteus, Calypso, Decis
25 WG. The research was carried out for
Idared, Golden delicious and Florina, on
tow variants for each variety. Phytosanitary
treatments applied for pest control were
supplemented with fungicides used to
combat major apple deseases. Until
blooming tow treatments were applied for
each variant, and after the petals fall,
treatments were carried out at warning.
Observation and measurements were
performed after the treatments and they
showed, at the end of each generation, the
percentage of attacked fruits by the main
apple pests. These produsts applied in a few
treatments have provided a strong efficacy
in combating major apple pests: codling
moth (Cydia pomonella L.), fruit skin moth
(Adoxophyes reticulana Hb.), leaf miner
moth (Phyllonorycter sp.) and mites
(Panonychus sp.). To combat lepidoptera,
best result were obtained with Calypso 480
SC and Coragen insecticides, and also,
products such as Decis 25 WG and Proteus,
have ensured a good health in apple
plantation.
