Agriculture worldwide has suffered for millennia from voracious insects, primarily the locusts. Since biblical times, locusts have caused famine and loss. To predict its invasion impossible, to struggle, almost hopeless. Countries in Africa, the Caucasus, the Middle East and Russia are particularly familiar with this scourge.
In our time, the chemical industry has offered many ways to control insects, but they all have significant side effects: first of all, the emergence of resistant populations of pests and environmental pollution. In addition, the long-term experience of locust control shows that insecticides usually provide only a temporary reduction in the number and harmfulness in the places of their application, but in General, practically can not affect radically the course of long-term population dynamics. On the contrary, total processing destabilize the environmental situation due to the destruction of natural enemies, which extends the periods of mass reproduction for several years.
A microbiological method of control is also known – with the help of biologically active drugs that are aggressive towards locusts. Such tools have been tested in different regions of the world and have proven their effectiveness and environmental safety. Unlike the rigid chemical insecticides causing irreparable harm to ecosystems and legally forbidden in water and nature protection zones bioinsecticides belong to the substances which are not causing damage to recreational and water protection zones, are safe for warm-blooded animals including can be used in the areas of production of environmentally friendly products.
However, this method of control has many disadvantages: the fungus is very sensitive to weather conditions, quickly loses its effectiveness at suboptimal levels of insolation, temperature and humidity.
For example, in recent years, two drugs based on the fungus Metarhizium anisopliae var have been created and successfully introduced. acridum-Green Muscle (South Africa) and Green Guard (Australia), with high biological efficiency (85-95%) against migratory, desert, Moroccan locusts and mares. On the basis of Bassiana in the United States created two experimental anti-locust drugs-Mycocide GH and MycotrolK. however, tests of these drugs in the former Soviet Union showed their low efficiency in the climatic conditions of the former Soviet Union. Analysis of the tests showed that these drugs are extremely sensitive to UV radiation, temperature and humidity of the environment.
We have found a solution to this problem and offer an effective and safe method of plant protection from pests: a biologically active drug that effectively destroys the insect, combined with a unique method of its preservation - a microcontainer. This technology allows to protect plants even in water and nature protection zones, and also it is suitable for ultra-small spraying.
