How to control muskmelon downy mildew? There are three big differences between cantaloupe and melon!

Muskmelon is an annual trailing herb of cucumber in Cucurbitaceae. Its fruit shape and pericarp color vary from variety to variety. At present, it can be planted all over China. If it is not properly managed, diseases will occur. So, how to prevent downy mildew in melons?

Introduction to muskmelon!

1. Is melon a fruit or a vegetable?

Melon is a fruit, generally ripe in summer, the flesh can be eaten raw, taste sweet, but also can be processed into dried melon, preserved melon, melon juice, canned melon, melon wine, melon paste, pickled melon and other products.

2. What are the varieties of melon?

According to ecological characteristics, muskmelon in China is usually divided into thick-skinned melon and thin-skinned melon, thick-skinned melon mainly includes netted melon, winter melon, hard-skinned melon, mainly distributed in Xinjiang, Gansu and other northwest regions; thin-skinned muskmelon is widely cultivated in China. Northeast and North China are the main producing areas.

Second, how to prevent and cure muskmelon downy mildew?

1. What are the symptoms of melon downy mildew?

Muskmelon downy mildew is a kind of fungal disease aimed at the outbreak of muskmelon, which mainly harms the leaves and infects the disease at the seedling stage. Small water-like spots appear on the cotyledons, then expand into light brown spots, and gray-purple mildew layers grow on the back of the leaves when the humidity is high. When the adult plant is infected, the light yellow disease spot occurs on the leaf surface, and in the later stage, the disease spot becomes light brown or yellowish brown polygonal spot. under the condition of continuous rainfall, the disease spot expands rapidly or fuses into large patches, resulting in the upper curl or drying up of the leaves and the drying up of all the lower leaves.

2. What are the control methods of muskmelon downy mildew?

(1) Agricultural prevention and control: first, select varieties resistant to downy mildew; second, rational fertilization, increase the application of organic fertilizer, chemical fertilizer nitrogen, phosphorus and potassium; thirdly, choose irrigation in the early morning on a sunny day, no flooding is strictly prohibited, and moisture should be discharged in time after irrigation; finally, weed and vine should be removed in time to keep the plants well ventilated.

(2) Nutrition control: after flowering, urea 0.2kg, white sugar (or brown sugar) 0.5kg per mu were sprayed on water 40-50kg foliar once every 5-6 days, 4-5 times continuously, in order to enhance plant disease resistance and prevent disease.

(3) Plant control: at the initial stage of the disease, each mu of 0.2kg of pepper, ginger or garlic was mashed, wrapped in gauze, filtered in 50kg water, mixed and sprayed again after 3 days, and then sprayed once every 7 days, followed by 2-3 consecutive sprays.

(4) Pesticide control: chemical control can be sprayed, such as spraying 1000 times of 25% Ruidu wettable powder or 25% metalaxyl wettable powder, 60-70 kg per mu, once every 7-10 days, 3 times in a row, 4 hours after spraying in case of rain.

(5) removal and control: for diseased leaves with downy mildew, the diseased plants should be removed in time, burned or buried deeply, do not throw away the field or roadside, and avoid adjacent or continuous cropping with melons.

What are the differences between melons and cantaloupes?

Difference 1, the origin is different: muskmelon is mainly produced in the sunny northern region, the individual is larger, the shape is round or oval; muskmelon is mainly produced in the southern region with relatively large precipitation, the individual is small, and most of the shape is round.

Difference 2, different appearance: muskmelon is generally green, yellow, white, melon peel is thicker, it is easy to break after maturity; muskmelon has golden yellow, light green, white, thin peel, not easy to break.

Difference 3, sweetness is different: muskmelon produced in the north, sufficient light, sufficient photosynthesis, less consumption at night, the transformed sugar content is more, the melon fruit flavor is light and sweet; muskmelon is produced in the south, the precipitation is relatively large, the light is insufficient, the growing period is short, the transformed sugar content is less, the melon and fruit flavor is rich but not sweet.

The above is the introduction of melon downy mildew prevention and control methods, in fact, melons and melons are cucumber plants of the cucumber family, in essence, they all belong to the same kind of melons, but the varieties are different, there are three different ways to help you distinguish from each other.
