The Colorado potato beetle is a serious pest of Solanaceae crops in our country, especially potatoes. In order to reduce the chemical load in the field and prevent the development of resistance to chemicals in the Colorado beetle, this paper presents biological methods of protection using seasonal colonization by the predatory shield bug Picromerus and treatments with plant extract of amaranth of the Valentine variety (which, along with limiting the nutrition of the larvae of the Colorado beetle, stimulates growth and leads to an increase in the photosynthetic activity of protected plants). Additional treatment with amaranth extracts is recommended during the flowering period, which is critical for potatoes. Damage to potato leaves by Colorado potato larvae during this period can lead to significant decrease in productivity.
биологически х систем и агротехнологий Российской академии наук (г. Оренбург) 2 Оренбургский государственный аграрный университет (г. Оренбург) Аннотация. В статье изучена эффективность использования в кормовых рационах кавитированных концентратов (зерносмесь, пшеничные отруби) на синтез летучих жирных кислот (ЛЖК) и их количественного превращения в другие энергетические соединения в преджелудках бычков красной степной породы при выращивании и откорме. На основании проведённых исследований установлено, что при скармливании кавитированных зерносмеси и пшеничных отрубей подопытным бычкам синтезируемое количество летучих жирных кислот (ЛЖК) стало выше на 0
Providing the world population with high-quality and functional food products is one of the main tasks of modern scientists. The introduction and subsequent cultivation of new and rare crops makes it possible to expand the diet. Stachys sieboldii Mig, or stakhys, is a vegetable plant with medicinal properties. Of particular value is the underground part of the plant, its nodules. But even the leaves accumulate microelements, antioxidants and phenolic compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
