Causes of Zucchini Plant Death and the Latest Control Methods

With the improvement of cultivation levels, many vegetables can be brought to market out of season, and their planting areas are becoming increasingly widespread, but what comes along with this is the gradual worsening of diseases. The phenomenon of zucchini plant death gives farmers tremendous headaches. Below, follow the editor to take a look at the control methods for zucchini plant death.

I. Causes of Plant Death

1. Improper fertilization

Many farmers mostly use chemical fertilizers during production, which causes the organic matter content of the soil to continuously decrease, the soil to become compacted, beneficial bacteria to gradually decrease, and harmful bacteria to increase, making diseases worse and leading to zucchini plant death.

2. Gummy stem blight

This disease mainly harms leaves and stems, followed by the fruit. When leaves are affected, round or irregular lesions appear, and in the later stage the lesions crack open and are scattered with many small spots. After the stem is affected, oily lesions appear at the stem nodes, mainly secreting amber-colored gum. After drying, the diseased area does not shrink and split longitudinally; in severe cases, the stem rots and the plant lodges.

II. Control Methods

1. Fertilization should be based mainly on organic fertilizer or biological bacterial fertilizer. Before planting, apply 600-800 jin of decomposed farmyard manure per mu as base fertilizer, and it can also be combined with appropriate calcium, potassium, and boron fertilizers, which can meet the plant's demand for organic matter throughout the entire growth period, and can also increase beneficial bacteria and reduce diseases.

2. When transplanting, choose good weather. After planting the seedlings, do not rush to cover with soil. You can use a mixed solution of chitosan + thiophanate-methyl + streptomycin to drench the holes. After 2-3 days, once the root tips are exposed above the soil, then cover with soil. The soil should not be too deep; after watering, cover with film.

3. Do a good job of watering and fertilizing the plants. In the early stage, focus on root maintenance. It is recommended to apply amino acid or humic acid fertilizers. If conditions permit, fertilizers containing chitosan can be used, which can both prevent pests and diseases and regulate soil structure.

4. When plants develop gummy stem blight, spray a 500-600 times dilution of thiophanate-methyl or an 800-1000 times dilution of Manguling for control, spraying once every 5 days for 3-4 consecutive times, with good results.
