Mast^er ® — post-emergence herbicide with broad spectrum activity for controlling annual and perennial broadleaf and grass weeds.
The product has partial soil activity and is not washed away by rain within 2 hours after application. Weed growth is almost immediately halted after spraying (within 1-3 days). The next phase — yellowing (chlorosis) and / or appearance of reddish color on leaves (4-10 days). The final phase — gradual browning (necrosis) and death (7-20 days).
APPLICATION ON CORN
Due to the presence of an antidote in the composition of Mast^er ® 62 WG V.G., the herbicide is safe for corn (under normal vegetation) from emergence to the 10th leaf stage. Optimal herbicidal effect is achieved when Mast^er ® is applied at the 5-leaf corn stage — at this stage, the majority of weeds typically die. The product should be applied to actively growing weeds.
APPLICATION RATE
150 g / ha Mast^er ® 62% V.G. + BioPower ®. The application rate of the surfactant BioPower ® — 0.5% of the working solution volume. Use of the surfactant BioPower ® is mandatory! It is recommended not to mix Mast^er ® with fertilizers and organophosphorus insecticides.
PREPARATION OF WORKING SOLUTION
Working solution volume: 200-300 l / ha. Fill the sprayer tank with 1/3 water, prepare the master solution Mast^er ®, pour into the tank, turn on the mixer for 10-15 minutes, add the required amount of BioPower ®, and water, turn on the mixer for 10-15 minutes, close the sprayer lid, and check the spray nozzles (spray pattern should match the nozzle type; if there are deviations, correct them). The working solution should be used within 24 hours after preparation. If spraying is interrupted for 1 hour or more, the mixer should be turned on for 10-15 minutes before resuming work to ensure homogeneity. The selectivity of Mast^er ® is well tolerated by all common corn hybrids due to the presence of an antidote in the formulation. Regarding recommendations for use of Mast^er ® on sensitive hybrids, sweet corn, and certain lines, consult the seed originator companies. Under special weather conditions (temperature above 30 °C), within 1 week after spraying the field with Mast^er ® on corn, transitional symptoms such as slight bleaching may appear. On the other hand, under cold stress (frost), plants may acquire anthocyanic coloration. However, these symptoms quickly disappear without negative consequences for crop development or yield.
ADVANTAGES
Complete control of a broad spectrum of annual and perennial broadleaf and grass weeds, including docks and plantain. Safety for the crop due to the presence of an antidote. Faster action on weeds compared to other herbicides in the same group due to the surfactant properties. The product is not washed away by rain within 2 hours after spraying. Safe for all common corn hybrids and subsequent crops in crop rotation.
