• The technology should be an alternative to existing methods of permanent mowing
• The technology should have minimal negative effects on wheat
• The technology should show good results in the weather conditions of the regions under consideration.
On the wheat grain fields of the farms, spots of Rhaponticum repens (RR) appear in sizes from 5 x 5 to 40 x 40 meters. RR secretes special substances (derivatives of phenol, as well as repin, acroptilin and chircanin), which are dangerous for wheat because they inhibit its growth and development. At the same time, plants located in the epicenter of its root system are suppressed to the level that they may not produce seedlings at all. All parts of RR are toxic in the budding phase, especially in dry years. Its toxicity does not decrease after drying. On average, in the fields of the enterprise, the area of RR varies distribution from 0.5% to 2%. The problem is aggravated by the fact that machine operators, in some situations cause its further spread in the fields.
Scale of the problem: Almost all farms in the Central and Northern regions of Kazakhstan. Average spots 10x10 to 20x20 meters. For the distribution of the fields of 0,4 – 1,5%
