Abstract:
An experiment was set up in 2013 for watermelons, which had as purpose the identification of some treatment variants
which would prevent the occurrence of the attack of some pathogenic agents specific to them. The variants of treatment
were the following: V1 not treated control sample, V2 – Topsin 500 SC-0.1%, V3-Alert-0.1%, V4 - Folpan 80 WG0.15%, V5 - Folpan 80 WG-0.1%+ Topsin 500 SC – 0.1%. The experiment was placed in randomized blocks, with
strict compliance to the experimental technique requirements. During the vegetation period, symptoms produced by
Fusarium oxysporum f. sp. niveum fungus which produces the fusarium wilting of watermellons (Velichi E. 2006), have
appeared differentially at each experimental variant. Other diseases, like the ones produced by the attack of
Colletotrichum lagenarium fungus which produces the curcubitaceae anthracnose or by the attack of Sphaerotheca
fuliginea fungus (Iacob Viorica, Hatman, M., Ulea, E., Puiu, I. 2000) which produces the mildew of cucurbitaceae, did
not manifest in the watermelons experiment which were subject to the experiment. Production’s harvest was done in
stages. The variants: V2 – Topsin, V3 - Alert - 0.1% and V5 - Folpan 80 WG - 0.1% + Topsin 500 SC – 0.1% have
achieved statistically differentiated productions against V1 – not treated control sample. Variant V4 – Folpan 80 WDG
– 0.15 % has achieved a production a bit larger than the not treated control sample, but without statistic insurance
