In course of the research there were determined the main reasons of winter garlic thinning. The research was realized in the conditions of the Republic of Belarus in 2010-2011. As a result of realized research it was revealed that the main reasons of winter garlic thinning was a clove kill (up to 40%) during winter period as a result of sharp rise in temperature, that leads to premature crop growth and nutritive elements reserves exhaustion in the pulpy scale and unsatisfactory quality of planting material (clove affection by bacteria, fungi and also thrips damage). In spring-summer period garlic was parasitized by the dominant pathogen, downy mildew agent – Peronospora destructor (Berk) and alternaria blight (purple rot) agent – Alternaria porri (Ell.) Saw. A serious damage was brought to garlic plantings during vegetation by onion fly (Delia (Hylemyia) antique Meiq.), thrips (Thrips tabaci Lind.), gnawing noctuids and also rodents. Weed specific composition and density in garlic crops and plantings changed depending on the planting material and vegetative period duration (in annual and biennial crop).
