Fishpond application note
1. When several drugs are mixed and applied, they must be strictly followed according to the operating procedures. For example, bleaching powder, copper sulfate, and trichlorfon can not be used together with quicklime, because the first two cases will cause the neutralization reaction to fail or weaken the efficacy. In the case of insects, quicklime turns into dichlorvos and its toxicity increases 10 times. Another example is the combination of rhubarb and ammonia, the efficacy can be increased by 14 times. The production should be based on the different characteristics of the drug and be properly matched to avoid side effects.
2. When the incidence of fish rearing does not exceed 5%, it is generally not necessary to use a Quanchiposa method to prevent fish diseases. This can be prevented by using food-based drug bags and local water sprays near the food field. The incidence of raising fish is as high as 10%, and when the whole pool of drugs has to be used for prevention and control, it is necessary to accurately measure the water body. The application concentration is safer by using the lower limit or decrement of the constant. Within 24 hours after treatment, someone should be guarded and found that an abnormal phenomenon immediately flushed with water.
3. Notes on pesticide application: (1) When the water temperature is above 30°C, it is not advisable to use the whole pool to spray the pesticide. (2) During the morning when spraying, avoid direct sunlight, and it should be done in the evening. (3) Fish should not be applied at the end of floating head or floating head. (4) The feed should be applied after the feed is fed, and the order cannot be reversed. (5) The drug should be completely dissolved and then spilled, and from the wind up to the downwind, in order to increase the uniformity.
4. When using copper sulphate to kill lake trout, you can only concentrate on the downwind and do not spill on the whole pool. Sprinkle time should be arranged in the afternoon, otherwise it is easy to cause dead fish in the pond.
