Goal. To determine the technical efficacy of insecticide Belt Expert 480 SC, COP against grape leaf on vineyards, to determine its phytotoxicity and grape productivity indicators.
Methods. Field studies were conducted in Ovidiopolsky district of Odessa region, OJSC “Peremoga” on vineyards of Rkatsiteli variety, planting of 2010.
Results. In experimental plots when using the Belt Expert 480 SC, KC insecticide, the inflorescence damage 14 days after treatment was within 0.7—1.0%, and that of the brushes — 0.4—0.6%. On the reference variant, these figures were, respectively, 0.6% and 0.3%. The results of the studies showed that the insecticide Belt Expert 480 SC, KC with a flow rate of 0.25 l/ha was slightly less effective than Coragen standard preparation 20 KS with a flow rate of 1.0 l/ha. With an increase in the consumption rate of the test drug to 0.30 l/ha, its effectiveness on the grape leaf was practically at the level of the standard, both for the first and second generation of pests. The insecticidal activity of the studied drug Belt Expert 480 SC, KC at a consumption rate of 0.25 l/ha ranged from 93.7—94.2%. At a consumption rate of 0.30 l/ha, the effectiveness of the drug increased slightly and amounted to 95.6—96.2%, which was at the level of the reference drug Coragen 20 KS — 96.2—97.1%. When determining the yield of grape bushes in the control and experimental plots, there was no significant negative impact of prolonged drought and extreme temperatures during a significant part of the growing season. The estimated grape harvest from the experimental plots using the Belt Expert 480 SC, KC insecticide averaged 5.24—5.45 t/ha, the reference preparation of Coragen 20 KS was 5/47 t/ ha, which is 0.29—0.52 t/ha exceeded the yield of control bushes (4.95 t/ha).
Conclusions. Insecticide Belt Expert 480 SC, KC at consumption rates of 0.25 and 0.30 l/ha, applied to grape plantations against the first and second generations of grape leaf showed a high protective effect, which was respectively 93.7—94.2% and 95.6—96.2%. In the applied consumption rates, the Belt Expert 480 SC, KC preparation did not show phytotoxic effects on the annual growth and generative organs of grape bushes.
