УВАГА, ПАВУТИННИЙ КЛІЩ! ДЛЯ КОНТРОЛЮ – АКАРИЦИДИ ОМАЙТ ТА ОРТУС!
There are reports from the Kiev, Dnipropetrovsk, Mykolaiv, Kherson, Zaporizhzhya oblasts about the increase in the number of spider mite on soybeans (in the Dnipropetrovsk region found mites and corn). In the near future, a high temperature is expected in most regions of our country, which will cause a massive increase in the number of this dangerous pest. The spider mite can give 10-12 generations during the growing season, and also has high fecundity and the ability to rapidly propagate and reach a high population density under favorable conditions.
In some years, in the absence of effective control measures, the pest can lead to a loss of yield of 50% or more.
The rate of development and the intensity of propagation of the spider mite depend on the temperature and humidity of the air.
– The most favorable temperature for ticks is 29 … 31 ° C, in which the development of a mite from an egg to an adult finishes in 7.5-9 days. And also at this temperature, the greatest fertility of females is observed.
– The most optimal humidity is 35-55%. Higher humidity (over 80%) inhibits the development and reproduction of the spider mite.
As a result of damage to the spider mite, the normal function of the puffer apparatus is disturbed, the plants are lagging behind in growth, the leaves dry, prematurely fall, the plants die. In addition, for densely populated soybean with spider mite, the amount of beans is significantly reduced, they prematurely reach and crack, forming a succulent grain.
How to protect a culture from this dangerous pest?
Arista LifeSeens has two effective acaricides: Omate and Ortus.
The orthus is a highly selective contact acaricide that completely eliminates all moving mite stages (larvae, nymphs, imago), and also exhibits ovo-larivicidal action.
Omayt – effectively controls all moving stages of ticks, destroys ticks, resistant to other acaricides.
