MODE OF ACTION: It has a rapid lethal effect. It is toxic to larvae, nymphs and adults by contact and ingestion. It also disrupts the molting activity in nymphs. It is effective during the active periods of red spiders.

INFORMATION ABOUT RESISTANCE: The plant protection product named EFDAL FENROX is an acaricide classified as Group 21A according to its mechanism of action. Repeated applications of plant protection products with the same mechanism of action encourage the development of resistance. Therefore, in order to delay the development of resistance, do not exceed the total recommended number of applications of EFDAL FENROX within the same production season. In cases where the application must be repeated, be careful to use plant protection products with different mechanisms of action (other than Group 21A).

COMPATIBILITY: EFDAL FENROX can be mixed and disposed of with many fungicides and insecticides. However, before mixing large quantities, it is recommended to determine the physical suitability of the mixture by making a small amount of premix.

Apple - European Red Spider: Application should be made when an average of 8-10 live individuals are seen per leaf in periodic counts to be made on 100 leaves starting from May.

Vineyard - Two-Spotted Red Spider: The vineyard areas where it spreads should be kept under observation, chemical control is recommended when 5-8 pests are found on a leaf. If the pest density is above the threshold in counts made after the end of the effect period of the product used in the first application, the second application is made. In applications made before harvest, the application is stopped by taking into account the waiting period of the acaricide used. If the damage continues, application can be made after harvest.
