AMALGEROL®
A farmer in central Hungary treated his potatoes with a herbicide in the end of April. Shortly after they looked stressed showing for example yellow leaf borders (Fig. 1). He immediately sprayed 10 l/ha AMALGEROL as stress relieve to help the potatoes recover. 8 days later the plants looked already better.
A close-by potato field with the same variety was used for comparison. This "untreated check" was neither sprayed with herbicides, nor with AMALGEROL. All other parameter were the same.
Mid of May the AMALGEROL-treated potatoes had a higher canopy and greener leaves (Fig. 2, 3). A hand-sampling later on revealed 30 % more tubers for AMALGEROL-treated potato plants. Furthermore, fruit skin of the untreated tubers was with scab, whereas AMALGEROL tuber skin was smooth and healthy (Fig. 4, 5).
