Places that we did not spread the pre-emergent have burweed not blooming yet. Sprayed them with 2,4-D Amine 4 at 1 oz/gallon that is supposed to spray 1,000 SF. Included a non-ionic surfactant. Sprayed 1.5 gallons:
- west of the tack shed where the burweed is still lush green as opposed to what was spreayed last week that is looking pale to yellow.
- North of the grain bin
- small patches at the wash table next to the green house
- the patches of weeds missed in the backyard
