MBC Uses

• MBC fungicides can be applied to the seed or leaves of plants to kill fungal infections. MBC is effective in eliminating a wide spectrum of fungi that cause stem rots, powdery mildew, leaf spots and root and crown rots. MBC can both prevent fungus from harming plants and be used to treat infected plants. MBC can be used on cereal crops, fruits such as grapes, and vegetables. It is not effective against rust varieties of fungi.
  
  

How MBC Works

• MBC is a locally systemic fungicide. When it is sprayed on leaves and flowers of affected plants, it is capable of killing surface fungi and then moving into the leaves and flowers to kill fungi there. For example, MBC can move throughout a leaf's surface or from a flower's base to its stigma. It moves most efficiently through soft tissues, including shoot tips or early fruit, and less efficiently through mature leaves, fruit and other hard tissues. Its locally systemic nature differentiates MBC from contact fungicides, which only kill fungi on a plant's surface, and systemic fungicides, which move throughout the entire plant.
  
  

How and When to Use MBC

• MBC must be used according to the product's directions and only for fungi it is effective against. It is important to avoid spraying MBC on windy days as it may not fully cover the plant or reach the affected part. You will achieve better coverage by using a higher spray volume if possible.
  
  

MBC Problems

• If MBC is not used during the recommended time of year for a specific fungus, it will not be effective. For example, to prevent cottonball infections, plants must be sprayed when their shoots begin to grow and again as soon as they bloom. To prevent fruit rot, trees should be sprayed during late bloom or when fruits begin to appear. It is important to remember that MBC is not effective on all diseases, so it is crucial that buyers are able to correctly identify the fungus and choose the correct product. A larger risk related to MBC fungicides is that many fungi become resistant to it, making it ineffective against fungi that it was once able to control. To prevent resistance, MBC should be used with other chemical controls rather than exclusively. It is important not to exceed the number of applications indicated on a product's label and to alternate MBC with other products that are also effective on the fungus.
