July Strawberry Management Methods and Techniques

With the arrival of July, strawberry seedlings need to cope with hot weather. During this season, strawberry seedlings grow rapidly, but they also face multiple challenges such as high temperature, rain, floods and drought. The following are the key points of strawberry seedling management in July.

1. Control the prosperity

At the end of June, remove old leaves from the mother seedlings to control excessive growth, and do the same for the seedlings in late July. Be gentle when picking leaves to avoid damaging the plant, and remove the stipule sheaths. Spray protective agents such as mancozeb or methocarb in time after picking the leaves.

Use paclobutrazol before flowering and potassium phosphite after flowering.

2. Management of runners and seedlings

After the runners extend out, they should be guided in time to ensure that the seedlings are evenly distributed and avoid overlapping. When the seedlings have two leaves unfolded, add soil and press the vines to promote growth. If the number of runners is insufficient, you can spray gibberellins on cloudy or overcast days to promote growth, but be careful not to over-control growth.

3. Pull out the mother seedlings

When the seedling rate reaches more than 70%, remove the old seedlings and allow the first-generation seedlings to continue to grow runners in the original position, and control the growth of the entire field from late July to early August.

4. Field weeding

Manual weeding is recommended to avoid herbicide damage to the strawberry seedlings. If herbicides are needed, you can use appropriate amounts of fenvalerate, quizalofop-PhD (for grass weeds), lactofensulfuron-PhD, and beet tranquilizer (for broad-leaved weeds). Pay attention to the timing and method of using herbicides to avoid pesticide damage.

5. Disease prevention and control

1. Root rot prevention and control

When using the Cuiying and Mavis package, adjust the dosage and method of use according to different growth stages, such as flushing or root dredging during the seedling raising and transplanting periods, and dredging or root irrigation during the seedling acclimatization and hardening periods.

2. Leaf spot disease prevention and control

Bacterial leaf spot: Use copper series or antibiotics such as kasugamycin.

Fungal leaf spot: Use pyraclostrobin, mancozeb , myclobutanil and other agents alternately to improve the prevention and control effect.

3. Anthracnose prevention and control

Prevention is the key, especially before and after the rainy season. According to the weather forecast, spray a mixture of pyraclostrobin and myclobutanil in time to prevent anthrax infection.

The above are the key points for strawberry management in July. Doing these well can basically effectively promote the healthy growth of strawberry seedlings, improve disease resistance, and lay a good foundation for the subsequent growth cycle.
