According to phytosanitary monitoring, egg laying and larvae revival by bread bugs by a harmful turtle are currently underway in winter and spring grain crops of Ukraine. Larvae of the first age are not fed by their food begins from the second age, when they go to the ear.
In their development, the larvae of bedbugs go through five ages, reports the Main Directorate of the State Food and Beverage Service in the Kiev region.
Damage to the larvae of Eurygaster integriceps grains during the formation of milk ripeness leads to high-quality crop losses, deterioration of gluten, sowing and feed properties of grains.
Preservation of technological and sowing qualities of wheat and barley grains, namely in the phase of formation of milk ripeness, provides for protective measures: in the crops of durum and valuable wheat - in the presence of 2 or more larvae per m², on the remaining crops 4-6, in seed barley - 8-10 larvae per m².
The following plant protection products are effective: Aktara 25WG, Vg - 0.10-0.14 l / ha, Accent, CE - 1.5 l / ha, Altex, CE - 0.1-0.15 l / ha, Bi-58 new, ke - 1.5 l / ha, Decis f-Lux, 25 ES, CE - 0.3-0.4 l / ha, Karate Zeon 050 CS, SK - 0.15 l / ha, Mospilan, OP - 0.10 -0.12 kg / ha, Fastak, CE - 1.0-1.5 l / ha, Fury ,.e. - 0.07-0.10 l / ha and others. These drugs will be effective against many other related crop pests.
The optimal processing time against harmful bug bugs is the presence of 15-30% of third-instar larvae in crops, which indicates the revival of the vast majority of insects.
Crop protection must be carried out within 10-12 days from the completion of larval revival.
