Application of herbicides at treatment the areas for plantations of a pine and a spruce, created of ball-rooted seedlings

One of primary goals of a forestry in a coniferous-platyphyllous forest and a taiga zone of the European part of the Russian Federation -reproduction of highly productive valuable coniferous stands. It is known, that at clear fellings in productive site types negative influence of undesirable vegetation on cultures of coniferous plantations is greatest. The greatest danger to forest plantations the herbaceous vegetation represents to the first years after their creation, later -a coppice shoot and root off-springs deciduous tree species. The most effective method of control of undesirable vegetation is chemical, providing application of the modern herbicides which are meeting the requirements of modern ecological safety and registered for application in a forestry of the Russian Federation. In connection with growth of the areas of the plantations created by a ball-rooted seedlings, more and more actual there is a problem of their protection against negative influence of undesirable vegetation. In connection with specific features of a planting material of the modern forest selection-seed-growing centres and greenhouse complexes (height of stem, diameter of root collar, volume of container, biological age less than two years), developed before the recommendation for application of herbicides for a care of plantations demand updating. On the basis of the carried out researches the basic technology schedules of application of herbicides and their mixtures were developed at chemical treatment the areas under planting of pine and spruce plantations created of the ball-rooted seedlings.
