RESEARCHES CONCERNING THE POLLUTION DECREASE IN THE GRAPE WINE AND FRUCTIFEROUS TREES PLANTATIONS AT THE PHYTO-SANITARY TREATMENTS EFFECTUATION.

Abstract

Grape wine and the fructiferous trees are exposed on all time of the year to the attack of an important number of agricultural diseases and pests. For there controls are necessary 10…15 annual splashes with phito-sanitary substances, which pollutes strongly the air, the soil and the water layer from the respective plantations. The pollution is accumulated on the duration of 25…40 years (and just more) until they maintain in culture the respective plants. In the paper is presented the results obtained through the perfecting of the splashy equipments whereat they added devices for the losses recovery. They retrieved across 30 % from the substances unused by the plants, simultaneously with the improvement with 5…10% of the cover degree of leafs and trunks surfaces. If are utilized and another improvements of the technical equipment (the automatic control of the amount of substances delivered, very limitary spectrum of the drops etc.) it can obtain still more good results.
