What to do if cantaloupe leaves turn yellow

Cantaloupe is a hot-selling product in the fruit market and is also a favorite economic crop for many farmers. However, some melon farmers always have yellow leaves when growing cantaloupe. What should they do? In fact, there are many reasons for the yellowing of cantaloupe leaves, and melon farmers should treat them symptomatically. I will give you a detailed introduction below, and friends in need can take a look carefully.

1. Supplement trace elements

The most common reason for yellowing melon leaves is the lack of chlorophyll, and the main reason for the lack of chlorophyll in melons is the trace elements such as magnesium, nitrogen, iron and zinc in the soil. At this time, top dressing should be done in time, and it is best to apply some effective compound fertilizers. In addition, sometimes the lack of trace elements in the soil is also closely related to the salinization of the soil. If the melon leaves turn yellow in the current year, it is recommended to change the planting site in the second year.

2. You can spray foliar fertilizer

The yellowing of cantaloupe leaves is mostly caused by the lack of chlorophyll. At this time, you can spray some foliar fertilizers. It is best to spray some fertilizers with high chlorophyll content. When spraying foliar fertilizers, you should also apply some fertilizers containing nitrogen, phosphorus and potassium.

3. Yellowing leaves can be treated with medication

Yellowing of cantaloupe leaves may also be caused by bacterial leaf blight, which is often called bacterial leaf spot. After the disease occurs, it spreads quickly and should be treated with drugs in time. After seeing a small amount of yellow leaves, you should use drugs such as streptomycin or phytosporin in time to treat it, but try not to mix these drugs. When used alone, the treatment effect of bacterial leaf spot on cantaloupe will be more obvious.
