Today, the number of farms of Odessa, Nikolaev, Kherson, Zaporozhye and partly in Dnipropetrovsk and Kirovohrad regions, the proportion of infested plants in the fields reaches 70-100%.
In damaged plants, the first is yellow, then brown and eventually drying of leaves of different tiers, which definitely have a negative impact on their performance. This year the problem has become widespread and unprecedented scale that has created a significant threat of crop losses.
This same problem affected the soybean crops.
In particular, the beginning of the colonization of soybean crops spider mites in Kherson and Mykolaiv regions this year was observed in early July.
If in the future will stay dry and hot weather with daytime air temperatures up to + 30-32 ᴼС, it is not excluded, the rapid spread of spider mites on soybean crops in Central, Eastern and perhaps even the Western region. Yield losses of this crop, depending on the number of spots can range from 2 to 8 kg/ha.
To prevent significant damage to the soybean spider mite and possible crop losses, the company "Syngenta" recommends treating the crops at the appearance of the moving stages (adults, larvae, nymphs) of pest acaricide with long-term protective effect Vertimek 018 EC, K. E. (0,6 - 1,0 l/hectares).
Reports www.Agropravda.com due to translaminar properties of the active substance abamectin the period of protection of the drug over 2 weeks. This is enough to control two successive generations of spider mites. As a consequence, the development of phytophagous on plants completely stops.
