Anthracnose is a major disease affecting watermelon yield and must be included on the list. This disease can occur at any stage of watermelon cultivation, greatly increasing the difficulty of prevention and control. It is similar to wilt disease, and some people often confuse the two. Anthracnose is more common in humid southern areas and usually occurs on cold, rainy days. Paying attention to weather conditions is beneficial for the prevention of anthracnose, nipping the virus in the bud. Of course, it is necessary to use the right medicine to eliminate pests quickly. Next, I will introduce some medicines with good effects.
1. Mancozeb
Mancozeb is mainly used in the prevention and control stage and belongs to low-toxic pesticides, which can irritate the skin, so avoid direct contact with the agent during application. Mancozeb has a relatively obvious effect among similar agents, has a wide range of杀菌, and is not easy to develop resistance, so there is no need to worry about it becoming ineffective after a period of use. The biggest advantage of Mancozeb is that it does not require the combination with other medicines; just this one agent can effectively control the probability of disease and also increase watermelon yield while preventing pests.
Its application method is also very simple. Each spray needs to be done four or five times consecutively, with a interval of half a month between each application.
2. Chlorothalonil
Chlorothalonil has good adhesion and will not be easily washed off by rainwater when sprayed on crops, thus maintaining its effectiveness for a long time and reducing the amount of use and controlling costs. Chlorothalonil is toxic and can cause varying degrees of harm to animals and humans, especially during use, you must protect your eyes and skin.
When using Chlorothalonil, attention should be paid to the ratio. For every hectare, use 1000 grams of 75% Chlorothalonil wettable powder and add 1050 liters of water, then shake it evenly before starting to spray.
3. Fumigation Double
Fumigation Double is mainly used after the onset of the disease, but it also has some preventive effects and can be used in the control stage. After application, the effect can be seen quickly, making it a good choice for the treatment of anthracnose. Fumigation Double has low toxicity, but precautions should still be taken during use, as some people may experience allergic reactions.
Use 500 grams of 50% wettable powder in 250-400 kilograms of water, shake it evenly, and then start spraying.
In summary, all three medicines have relatively good effects. Overall, Mancozeb's effect is better.
