The recalculated amount of pesticides used in active substances per hectare of fruit trees and berries has decreased, according to the preliminary data on the use of pesticides in crop sowings and plantations for the 2019 harvest compiled by the Central Statistical Bureau (CSB), the CSB informed.
The amount of pesticides used for apples per hectare of plantation has decreased:
- from 1.28 kg in 2014 to 0.82 kg in 2019 or by 36%,
- cherries from 1.28 kg to 0.31 kg or 76% respectively,
- for plums – from 0.83 kg to 0.30 kg or by 63%,
- for pears – from 2.18 kg to 1.87 kg or by 14%,
- for raspberries, from 0,44 kg to 0,16 kg or 63%,
- for strawberries – from 0.44 kg to 0.06 kg or by 86%.
In 2019, 23% of plum areas, 25% raspberries, 30% apples, 31% cherries, 36% strawberries and 56% pears were treated with pesticides.
“The use of pesticides varies from year to year, depending on the weather. In dry conditions, various pests, which are controlled by insecticides, develop more, and in wet conditions, both disease and weed populations, which are controlled by fungicides and herbicides, respectively. 2019 was relatively drier – especially spring and the first half of summer, therefore diseases developed less and fungicides were used little to control them, but in some fields they were not needed at all, ”Vents Ezers, Director of the Plant Protection Department of the State Plant Protection Service, explained to the media. .
The amount of pesticides used per hectare of sown and planted areas in open field vegetable areas has increased for carrots, beets and onions, but decreased for cabbage.
In 2019 per hectare:
- the amount of pesticides used in carrot sowings increased from 2.09 kg in 2014 to 3.34 kg in 2019 or by 60%,
- onions – from 3.03 kg to 3.49 kg or 15%, respectively,
- table beet – from 0.70 to 1.78 kg or by 153%.
The amount of pesticides used per hectare in cabbage plantations decreased from 1.01 kg in 2014 to 0.86 kg in 2019 or by 15%, but in potato plantations from 2.05 kg to 2.00 kg or by 2.4%, respectively.
In 2019, 87% of cabbage, 89% of onion plantations, 90% of carrots and beet crops were treated with pesticides, mainly herbicides to control weeds. Pesticides were used in 67% of potato plantations.

The increase in the amount of pesticides used per hectare of sown carrots in open field vegetables was influenced by the increase in the use of herbicides from 1.83 kg in 2014 to 3.10 kg in 2019 or by 69%, for beets – from 0.69 kg to 1.68 kg, respectively. or by 143% and onions – from 1.15 kg to 1.96 kg or by 70%.
The increase in herbicide use was explained by Lake with seasonal differences in different years, which affect the range of herbicides used: “Effective weed control in vegetable areas is a key condition for harvesting. dry weather necessitated the application of post-emergence herbicides, such as prosulfocarb and metamitron, which had relatively higher consumption per hectare. “

In 2019, fungicides were most used for apples and raspberries – 78% of the total amount of pesticides used for both apples and raspberries, pears 66%, cherries – 62%, strawberries – 77%, potatoes – 84%.
In turn, herbicides for weed control are most used in table beet sowings – 94% of the total amount of pesticides used in table beet sowings, in carrot areas, respectively 93%, in cabbage plantations – 75%, in onion plantations – 56%.
Last year, insecticides were used very little – only 21% of pears and 11% of the amount of pesticides used in cabbage plantations were insecticides.
The use of pesticides on crops is also affected by the use of pesticides containing heavier active substances. In 2019, three herbicide active ingredients – aclonifen, pendimethalin and prosulfocarb – accounted for 85% of all pesticides used in carrots to control weeds in carrots,
In table beet areas, 48% of the total amount of pesticides used was one herbicide active ingredient – metamitron, the use of which per hectare of beets increased from 0.93 kg in 2014 to 1.49 kg in 2019 or by 60%.
In onion areas, 87% of the total amount of pesticides used in onions consisted of the herbicide active ingredients aclonifen, pendimethalin and a fungicide, which provides plant protection against fungal diseases – mancozeb.
