How to save strawberry drug damage

In the process of strawberry cultivation, improper concentration, improper time and improper mixing often lead to drug damage, some abnormal drug damage often occurs a few hours after spraying, while some chronic drug damage takes time to show, which will affect the yield and quality of strawberry fruit. So how to remedy the strawberry drug damage? Let's get to know it with the editor.

1. Symptoms of strawberry drug damage

1. Spots

It mainly occurs on leaves or fruits, and the common spots are brown spot, yellow spot, withered spot and so on, which are different from disease spots. The spots caused by drug damage are unevenly distributed on the plant, some are light and heavy, the disease spots are large and small, and the shape is not consistent.

2. Etiolation

It mainly occurs on the leaves, the light is the leaf yellowing, the heavy is the whole plant yellowing, the yellowing caused by drug damage is not the same as the lack of nutrient elements. Drug damage is often yellow leaves to withered leaves, according to the degree of climate change, high temperature, fast yellowing, low temperature, slow yellowing.

3. Deformity

Deformities mainly occur on leaves and fruits, which often cause curly leaves, clumps, root swelling, deformed flowers, deformed fruits, etc., which are different from those caused by viral diseases, which are more common in the early stage, mainly in local areas, and sporadic in the later stage. Often mixed in the resulting leaves and fruits.

4. Wilt

Drug-induced wilt is often a symptom of the whole plant, mostly caused by herbicides, drug-induced wilt has no disease center, most of the occurrence process is slow, first yellowing, then dead seedlings, rhizome dredging tissue no browning.

5. Growth stagnation

The drug damage will inhibit the normal growth of the plant and make the plant grow slowly. The common drug damage is caused by triazoles and herbicides. Compared with the symptoms caused by other diseases, the drug damage is often accompanied by drug spots or other drug damage symptoms. The main manifestation of the disease is poor root growth.

II. Remedial measures

1. Replenish fertilizer and promote seedlings

For the drug damage with mild symptoms, such as leaf yellowing and leaf edge scorching, appropriate amount of nitrogen fertilizer and compound fertilizer can be applied, or foliar fertilizer can be sprayed to promote plant rejuvenation.

2. Irrigation

As for the drug damage caused by herbicide irrigation and the use of herbicides under the film, fertilization and spraying can not be solved, only watering can reduce the concentration of herbicides, reduce the accumulation of harmful substances in roots and alleviate symptoms.

3. Spray the relieving agent

If it is caused by spraying alachlor, gibberellin or 0.2% soap can be sprayed to alleviate the damage caused by organophosphorus pesticides.

4. Spray water

If the pesticide occurs after spraying the wrong pesticide, the clear water can be sprayed in time to wash the chemical on the surface of the plant clean, and if it is an acidic agent, an appropriate amount of plant ash or lime solution can be added to the water; and if it is caused by an alkaline agent, vinegar can be added to the water. At the same time, we should pay attention to ventilation, cooling and humidity, in order to facilitate the discharge of harmful gases.

5. Pick leaves and fruits

After the damage to the leaves, the faded leaves should be removed in time, so that the leaves have lost photosynthesis and will only consume nutrients. Timely removal can not only save nutrient consumption, but also curb the permeation and transmission of chemicals in the plant. In addition, the same is true for malformed fruits, which need to be removed in time.
