With all the wet weather we’ve had this year fungal diseases are already running rampant and the inevitable insect problems are appearing too. The wet weather also makes using synthetic pesticides a little difficult because they barely have time to dry before it rains and washes it off again, so lots of gardeners are using less toxic, homemade versions of insect and disease sprays. Here’s a recipe for a homemade formula that you can use on just about any of your plants.
This is an all purpose fungicide/insecticide spray.
Mix 3 TBS baking soda
2 TBS ivory soap
1 TBS vegetable oil
In a gallon of water. The baking soda is a natural fungicide; the soap an insecticide; and the oil a surfactant and insecticide.
Pour into a sprayer after the soap dissolves and apply to plant leaves—top and bottom-- every few days. When trying this recipe on new plants, spray just a few leaves or a stem and wait 3-4 days to make sure that the plant doesn’t have an adverse reaction.
