What should fungicides be irrigated to prevent diseases and insect pests?
Fungicide irrigation root disease and insect pests should pay attention to what? The following points should be noted: First, the choice of drugs should be reasonable: choose a strong targeted, and has a high curative function of the fungicide, do not blindly use drugs, as far as possible to reduce waste, prevent delays in prevention and control opportunities, reduce efficacy. Second, the use of concentration should be appropriate: fungicides should be mixed with amino acid liquid fertilizer or hormones that stimulate root development as much as possible, and the concentration of liquid medicine should not be higher than 1500 times to prevent soil moisture content (soil moisture concentration around crop roots) from being too high. Do not irrigate the shed with large water within 7 days after root irrigation, otherwise the concentration of liquid medicine will be reduced and the effect of sterilization and disease prevention will be affected. Third, soil biology should be balanced: the selected pesticide fungicide applied to the soil can not destroy the biological community and ecological balance in the soil. If the shed has been used bacterial fertilizer, try not to use fungicides root irrigation disease prevention. If crop diseases begin to occur and spread rapidly, it is another matter, that is, do not consider the problem of bacterial fertilizer, and immediately implement root irrigation to reduce losses. IV. Phytotoxicity remedy should be timely: if phytotoxicity reaction occurs after root irrigation, such as plant wilting, yellowing, stagnation and other symptoms, remedy should be carried out in time. Remedy measures: quickly irrigate water once to dilute the concentration of liquid medicine in the soil; spray and irrigate roots with rooting agent or Aiduo Harvest or Yunda 120 in time to alleviate phytotoxicity and promote the root system to recover vitality as soon as possible, so that the plants can grow normally.
