Fiesta 09-10
In the fall of 2009 Fiesta was applied to dandelion, black medic, narrow leaf plantain. Results were good but would there be regrowth the next spring?
The fall treatments involved using 3 rates
Low label rate 200ml/m2
High label rate 400ml/m2
2x label rate
High label rate 400ml/m2
2x label rate
Fall results showed good results with dandelion, black medic. However narrow plantain was only about 40% weed reduction.
By the end of April, With one treatment in fall
Dandelion by spring close to the same amount as the fall. Black medic was less with higher rates.
Plantain - no change- perhaps because it doesn't grow early spring??

Fiesta re-growth '10
Fiesta re-growth '10
Evaluate regrowth of weeds after 2 applications
4 types of weeds Clover, Narrow Plantain, Wide Plantain, Dandelion. Individual weeds were tagged so it could be seen if there was regrowth
Treated June 7 and July 7 with Spot treatment to coverage to wetness
Results were evaluated one month after second treatment
Dandelion and both plantains showed good results.
Clover not as good.

Weeds treated with 2 Fiesta applications one month apart showed a good weed control.
Organosol '10
Cheese byproduct that contains Citric and lactic acid
Mix 25% Organosol plus 3% surfactant ( LI700) + 72% water
Applied at 200 ml/m2
5 treatments 2 weeks apart starting end of May
Some yellowing of grass 2-3 hrs after spray which grew out after one cutting.
Did good control of clovers, black medic and oxalis
Organosol did not do very well as a dandelion treatment

Is there any synergy with Organosol and Fiesta together?
Sprays end of September, end of October
