Abstract
The UN Food Agency announced 2020 as International Year for Plant Protection. About 40% of crop yields losses are caused by pests and diseases. Due to this, millions of people suffer from hunger. Therefore, there is a need to seek for and select environmentally friendly and highly effective products that will increase yields and the production quality. In 2017-2018, in the Novosibirsk Region, it was shown in field trials and production experiments that the biopreparation Phytop 8.67 based on the bacteria of the genus Bacillus has antagonistic activity in relation to carrot alternativeariosis (the causative agent is Alternaria dauci carrots, reduces the plants prevalence during the vegetation period, and also has a growth stimulating effect. The prevalence of brown leaf spotting decreased by 4.8 times, and the biological effect of Phytop 8.67 in two years with respect to the disease progress was 63.2 (after 10 weeks) and 78.4% (after 12 weeks). In the experimental variants, the plants were statistically more reliable than the control ones and were more foliated on all the dates of accounting. Application of biospecimen increased 1 root crop weight by 1,7 times in the control variant, in finedelivery experiment and by 1,4 times - in industrial one. Due to this, the authors recommend applying Phytop 8.67 specimen as a fungicide, a growth stimulator in order to increase carrot productivity.
