- The solution should not depress crop plants in the crop rotation.
- The solution can include both mechanical processing of potato row spacing and the use of herbicides that effectively combat weeds common in the fields.
- Should work on potatoes grown under irrigation.
Details of the Technology Call
The company is engaged in growing potatoes, with up to 20% loss (decrease) in yield annually due to the spread of the following main weeds. Solánum nígrum 5-15 plants per sq. m., Echinóchloa crus-gálli 3-10 Rast. on m, Amaranthus retroflexus 2-5 plants per sq. m, Atriplex canescens 5-10 plants per sq m, Chenopódium álbum 5-10 plants per sq. m.
At the moment, the main method of control is chemical, in particular,the herbicide Stomp 3 liter/hectare, Gezagard 3 l/h before germination, Zencor 0.7 l/h, Titus 50 g/h. When using these drugs, Solánum nígrum is not destroyed, white Atriplex canescens is destroyed only 30 %. The company is interested in finding new effective and cost-efficient solutions to mitigate (control) the spread of the above-mentioned weeds. Parameters of planting method: row spacing of 75 cm followed by combing.
Scale of the problem: all sown area 300 hectares. The crop Rotations of potatoes (P) is: P-carrot-P-carrot-cabbage-P-pair(green manure), P –onions-carrots, P-P-P pair(green manure), P- beets-onion-cabbage-P
