  • That stuff works for fungus gnat larva as well.

  • I've been hit with the same weather conditions this year with some days the fog never burned off. I've been using "Dyna-Gro Pure Neem Oil "Organic Leaf Polish". When I apply it (following the directions) I spray like giving the leaves a shower. It has really helped a lot!

  • hows any of your melons done good

  • that is pennicillin. they spray it on pear trees they are so susceptible to fungus. i would be careful using an antibiotic like that on my plant or introducing it to the soil. i would buy sulfur in powder form and spray it on the plants. it is good for the soil and it is 'organic' in that sulfur occurs in nature. you're over paying for that as farm store probably sell it dirt cheap. i have also used baking soda as foliar spray with good effects not as good as sulfur but pretty good.

  • you have such dense area growth that plant disease is much more likely

  • Surfactants (dish detergent , 1-2 tbls/gallon of water) ; Antitranspirants (?) ; Fungicides (Sulfer based, copper based - do not apply in full sun) - Safer is big nmae and is OMRI listed; Baking Soda (as preventative - solution made with surfactant ) ... Google these or read up a bit more...

  • Hi John, Full sun and good air circulation around the plants helps prevent powdery mildew. When the veggies are planted so close together they shade each other and create poor air circulation. The cool temps and morning fog sure do not help either!

  • ih thanks for the tip i did not know that
