Title

Italian Zeolitites in the Control of Grey Mould and Sour Rot and Their Effect on Leaf Reflectance, Grape and Wine

Francesco Calzarano; Leonardo Seghetti; Giancarlo Pagnani; et al. Agriculture 2020. doi:10.3390/agriculture10120580

Other claims from this paper (5)

Intervention effect Both zeolitites significantly reduced grapevine grey mould and sour rot infections.
Intervention effect Only vines treated with zeolitite 2 days before harvest, especially with copper zeolitite, showed a decrease in leaf reflectance.
Intervention effect No differences in yield composition related to the time of zeolitite application were recorded.
Intervention effect Samples from vines treated with zeolitites showed increases in grape soluble solids and wine alcohol content.

Other claims from this paper (8)

Intervention effect Chemical spraying in the first season did not keep its effectiveness in the second season.
Intervention effect By the delaying method the tea yield may be expected to increase in the first season.
Association The later the plucking time in the third season, the less the growth in the next year.
Association The later the plucking time in the third season, the number of shoots increased somewhat.
Intervention effect The quality of tea was not remarkably affected in this test.
Recommendation It is necessary to spray chemicals again in the second season to retard shoot growth.
Recommendation It is unprofitable to delay tea growth extremely in the third season.
Recommendation It is favourable to apply the delaying method in the plucking program to regulate plucking time.
