The plant protection product calculated over the recommended dosage is first mixed with some water in a separate container. The tank of the application machine is half filled with water. While the mixer of the machine is running, the mixture is added to the tank. The mixing is continued and the tank is completed with water. Mixing process continues until the application is completed. Use the prepared mixture on the same day.


If the beneficial insects along with aphids are intensive in the field controls against cotton aphids in cotton, the application should be postponed. Fighting is recommended when an average of 25 aphids per 1 leaf is detected in the field.

In tomato, peach aphid is entered in the field in the direction of diagonals and applied in 3-5 steps, 20-40 leaves are applied when an average of 10-20 pests per leaf is seen. However, the effectiveness of the benefits should be taken into consideration before deciding on applications by observing parasitoids and predators.

In peach, application should be done when 7 dish branches are found in 50 trees until determination of flower buds against peach aphid and 3/4 of the population turns into a winged form.

In the eggplant, the area determined to be contaminated with whiteflies against tobacco whitefly is entered in terms of diagonal. In every five steps, 50 leaves are collected from the lower, middle and upper leaves. Chemical combat is applied when there are 5 larvae + pupae per leaf.

Against cotton aphid in watermelon, it is entered into the field in the direction of diagonals and one leaf is cut from the fresh leaves and shoots of the plants by chance in 3-5 steps. As a result of counts made with loupe on 20-40 leaves; If the number of pests per leaf is 10-20, it is necessary to start fighting. However, the effectiveness of the benefits should be taken into consideration before deciding on applications by observing parasitoids and predators.

INTEGRATED STRUGGLE AND ANTI-RESISTANCE STRATEGY: It is applied according to an implementation plan determined at the beginning of the season. Local economic harmful thresholds should be observed. Plant protection products with different effect mechanisms should be used in case of change.

INFORMATION ABOUT RESISTANCE: PLEZİN 50 WG plant protection product is an insecticide classified as Group 9B according to its mechanism of action. Repeated applications of plant protection products with the same mechanism of action promote resistance development. For this reason, in order to delay resistance development, do not exceed total application number of PLEZIN 50 WG during the same production season. In cases where the application should be repeated, pay attention to the use of plant protection products with a different mechanism of action (other than Group 9B).

MIXABLE CONDITION: It is recommended to make a pre-mix test before making a mixture.
