The Latest Preventive Measures for Strawberry Bacterial Wilt and Seedling Death

During strawberry cultivation, bacterial wilt and seedling death can occur, greatly affecting yield and income and causing huge economic losses for farmers. So what causes strawberry bacterial wilt and seedling death? Let's take a look at the detailed introduction.

1. Causes

The main cause of strawberry bacterial wilt and seedling death is a sudden drop in temperature; persistent low temperatures lead to the reproduction and infection of Rhizopus and Botrytis, thereby worsening the bacterial wilt and seedling death. In addition to the drop in temperature, it is also related to variety, soil moisture content, fertilizer type, and cultivation management.

2. Preventive Measures

1. Choose good varieties

Strawberries have strong adaptability, but a sudden drop in temperature makes it difficult for their root systems to absorb water, hindering water transport and resulting in weak cold resistance. Many growers mostly choose early-maturing varieties, whose cold resistance and stress resistance are weaker than those of open-field cultivation, so the mortality rate is high; therefore, good varieties should be selected when planting.

2. Apply more organic fertilizer

When applying base fertilizer, increase the organic fertilizer content, especially paying attention to the phosphorus and potassium fertilizer content, and pay attention to the application rate of nitrogen fertilizer, so as to avoid excessive nitrogen uptake by seedlings, which causes dark green leaves, overly late aboveground growth, and makes bacterial wilt and seedling death highly likely to occur when low temperatures are encountered; it also delays flower bud differentiation and fruiting, and affects yield.

3. Pay attention to low temperatures

Always pay attention to weather changes. Before low temperatures and cold arrive, take preventive measures in advance. Flat covering can be used, and straw curtains can be added at night; when it clears up or warms up, promptly remove the film and curtains, which can prevent bacterial wilt and seedling death.

4. Replant in time

When planting, reserve some insurance seedlings for use in case of pests, diseases, or man-made damage. When plants are damaged or die, promptly pull out the diseased and dead seedlings, clear the root zone soil, and promptly fill in soil and replant.

5. Spray chemicals for control

Once seedlings are injured, immediately spray chemicals and growth regulators to help the plants recover as quickly as possible, enhance disease resistance, and avoid infection by pathogens.
