Description

Опыты показали, что 0-метил, 0-(3- бромкумарин-4-ил)карбонат превосходит по активности используемые в сельском хоз йстве фунгициды, его активность сохран етс  на высоком уровне при низких концентраци х, в то врем  как у штатных фунгицидов она значительно падает.Experiments have shown that 0-methyl, 0- (3-bromocoumarin-4-yl) carbonate is superior in activity to fungicides used in agriculture, its activity is maintained at a high level at low concentrations, while in regular fungicides it drops significantly.

Преимущества нового препарата очевидны из его универсальности; он эффекти0вен как протиив возбудител  болезней томатов , так и против возбудител  болезней на рисе. Кроме того, 0-метил, 0-(3-бромку- марин-4-ил)карбонат менее токсичен, чем штатные фунгициды.The benefits of the new drug are evident from its versatility; it is effective both against the pathogen of tomato diseases and against the pathogen in rice. In addition, 0-methyl, 0- (3-bromo-marin-4-yl) carbonate is less toxic than regular fungicides.
