    I need to spray some grassy weeds-- crabcrass, goosegrass, etc.-- but the temperature is constantly above 100 degrees. Is it too hot to spray? What should I use.

    Is the lawn in good health otherwise? Are both weeds and lawn still growing? Then it is ok to use the new herbicides I mentioned to you previously. In fact they should work quite well. Earlier this year, I had a problem with the herbicides not working very well. Temperatures were under 80, no sun for weeks on end, and heavy rains.
