Digital technologies for grain protection

A remote monitoring system has been created for the monitoring of the condition of the stored grain. It includes a set of grain mass measurements combined with a personal computer. The measurement provides prompt and tolerance control of the basic parameters of the grain mass condition – temperature, relative humidity and the presence of harmful insects and mites in the mode of on‑line and in dynamics.

Effects of abamectin on lesser grain borer, Rhyzopertha dominica F. (Coleoptera: Bostrichidae), infestation on some stored grains

Background Modern methods of stored wheat grain protection from insect pests strive towards optimizing the use of different techniques and methods within integrated pest management (IPM) programs. One of the methods of integral grain protection is the application of natural originating insecticides. Main body The potential of the natural origin synthetic insecticide abamectin (a product of soil bacteria, Streptomyces avermitilis fermentation) on the grain borer, Rhyzopertha dominica F. (Coleoptera: Bostrichidae), in stored wheat, barley, ray, oats, and triticale was evaluated. The evaluation was conducted in 3 rates. The effects of its application on the infestation of R. dominica on certain physical and chemical traits of cereal grains were examined. The efficacy of abamectin after 7 days of exposure, in all applied dosages, was low (< 56.5% in wheat and < 30.5% in other grains). Abamectin efficacy was significantly increased after 14 days of exposure. R. dominica mortality was 99.0 and 100% after 21-day exposure at the abamectin rates of 0.5 and 1.0 mg kg−1, respectively. Ten weeks after grain treatment, the 3 examined rates prevented the emergence of progeny. The amount of the damaged grains and dockage, as a nus-product of feeding of R. dominica larvae and imago, compared to the untreated, infested sample was significantly smaller, which represents a positive aspect of abamectin application. The application did not change significantly the moisture, protein, and ash contents, in comparison to the control. Conclusion Positive aspects of the abamectin application on different grain species (wheat, barley, rye, oats, and triticale) caused the highest rates of R. dominica mortality after 21 days of exposure where a total prevention of progeny emergence and absence of changes on technological grain properties occurred.

Efficiency of seed treatment against soil pytophagous on corn

Biological and technical effectivity of systemic insecticides (Kruizer 360 FS; Poncho 600 FS, TN; Gaucho Plus 466 FS, ТН; Fors Zea 280 FS) for corn grain protection from soil phytophagous was studied. Significant increasing of corn on grain yields was obtained during using of this drugs.
