In order to establish the selectivity of the Cleranda herbicide (375 g/l metazachlor
+ 17.5 g/l imazamox) in the field of the Soybean experimental station - Pavlikeni, a
field experiment with soybean variety “Richie” was carried out.
The trials were conducted in non-irrigating conditions on medium-leaved
black earth and includes the following variants: V1 - Control without weeds; V2 -
imazamox 40 g/l (Pulsar 40) - 80 ml/da + Dech - 100 ml/da (standard); V3 - 375 g/l metazachlor + 17.5 g/l imazamox (Cleranda) - 120 ml / da; V4 - 375 g/l metazachlor
+ 17.5 g/l imazamox (Cleranda) - 150 ml/ da; V5 - 375 g/l metazachlor + 17.5 g/l
imazamox (Cleranda) - 120 ml/da + Dech 100 ml/da and V6 - 375 g/l metazachlor
+ 17.5 g/l imazamox (Cleranda) - 150 ml/da + Dech 100 ml/da.
It was found that: A two-component herbicide Cleranda (375 g/l metazachlor 17.5
g/l imazamox) applied alone - 120 and 150 ml/da or with adjuvant Desh at the
growth stage tow- trifoliate leaves of soybean (BBCH 12-13) had high selectivity
(1.0 ± 1.5 score) for culture.
Cleranda (375 g/l metazachlor 17.5 g/l imazamox) at the applied doses (120 and
150 ml/da with or without added adjuvant Dash - 100 ml/d) under specific agrometeorological
conditions does not had a negative effect on the soybean “Richi”
variety for seed yield formation.
