{"id":15158720233842,"title":"Dithane M-45 Fungicide - 1 Lb.","handle":"dithane-m-45-fungicide-1-lb","description":"

Dithane M-45 Fungicide delivers targeted disease prevention through an 80 percent mancozeb formulation that acts as a broad-spectrum protectant barrier. Optimal control requires integration into a scheduled preventative spray program, since the chemistry blocks fungal colonization before it establishes. The 1 lb container supplies adequate volume for routine seasonal applications across both residential gardens and commercial greenhouse setups.

This formulation supports flexible deployment in outdoor landscapes, agricultural fields, and enclosed grow rooms. Vegetable producers use it to shield tomatoes, potatoes, corn, squash, cucumber, melon, and papaya, while nursery operations frequently apply it to ornamental stock. Specialty plants like African violets, ferns, and dendrobium orchids carry explicit labeling for treatment.

Roses: Industry standard for suppressing black spot
Field and garden crops: Controls leaf spots, rust, downy mildew, and botrytis
Solanaceous and cucurbit vegetables: Blocks early blight, late blight, and anthracnose

Prepare each application by combining 1.5 tablespoons of product per gallon of water, then spray as a thorough foliar cover. Incorporating an agricultural surfactant strengthens results by ensuring a more uniform spray deposit, accelerating foliar redistribution, and increasing retention during wet weather windows. Follow the manufacturer label for storage and handling guidelines.
