Adventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence
One of the most destabilizing factors of crop production is weed infestation of crops. Despite annual herbicide treatment, weed infestation of crops of winter wheat remains high, with a predominance of annual dicotyledonous weed with a higher proportion of drug resistant on the basis of 2,4-D. We also notice increased range and density of perennial dicotyledonous weeds. New combinational herbicide called Cayenne, manufactured by LLC "Agro Expert group", which in its composition contains two active substances: thifensulfuron-methyl (500 g/l) and florasulam (170 g/l), highly inhibits both annual and perennial dicotyledonous weeds. According to the working program of the registrant's company we have tested Cayenne on crops of winter wheat in spring in the tillering phase and the formation of the second internode. It is shown that its use in doses of 0.025 and 0.035 kg/ha in mixture with 200 ml/ha of surfactant-Bit 90, W provides effective suppression of annual and perennial dicotyledonous weeds (90 – 100 %). The negative effect on the culture was not observed. At the same time, within 2-3 days after herbicide application we observed cessation of growth, chlorosis, dieback of growing points of weeds. Complete death was observed after 15 – 20 days
Ragweed plant became quarantine malware on the
territory of Southern Russia. In the Krasnodar region it
has been extended to the territory of more than 4.62
million hectares. In the areas of its growth, it causes
great damage to agriculture. By developing a strong
root system and aboveground, it inhibits the row crops,
especially sunflower. Another problem with this weed
is producing large amounts of pollen that causes
allergic reactions in the majority of residents of the
province. This article discusses the importance of
using modern methods of ragweed oppression,
including chemical and biological methods in
sunflower crops
Intensification of agriculture during the twentieth
century was accompanied by an increase in
international trade, resulting in the resettlement of
many species across continents. As a result of these
processes, many adventives species have become
economically significant and dangerous plants in agro
and urban biosensors. One such plant is Ambrosia
artemisiifolia L., imported from North America to
Russia. The use of chemical means of suppression of
A. artemisiifolia L. often does not give positive results
in agrocenoses, because of its biomorphological
features. In urban areas, within the boundaries of
sanitary zones, the use of chemicals is prohibited.
Therefore, the most promising direction in the
suppression of ragweed ambrosia is the ecologies
method. The article discusses the possibility of using
an ambrosia leaf beetle in the feeding of ragweed in
the territory of Russia
