Greenhouse loofah pest control comprehensive prevention method

With the continuous expansion of the loofah planting area in our city, pests and diseases have gradually increased. To improve its yield and quality, the following prevention and control methods can be adopted:

First, agricultural control. 1. Implement rotation; 2. Select anti-(resistant) disease seeds and strictly disinfect seed; 3. Cultivate strong seedlings and improve resistance; 4. Clean the garden, remove diseased leaves in time, remove diseased plants; Scientific management, balanced fertilization.

Second, physical control. For greenhouse cultivation, additional insect nets are added to the ventilation openings or yellow booby traps are suspended in the sheds.

Third, biological control. Insect pests, protect and use a variety of natural enemies, such as dragonfly bees, seven-spot ladybugs and so on.

Fourth, chemical control. The main control objects are damping-off diseases, downy mildew and other diseases, as well as insect pests such as aphids, whiteflies, and leafminers. To achieve the right medicine, alternating medication, strictly control the dosage and safety interval

Anti-Respiratory

Respiratory disease is a common disease, frequently-occurring disease, the main lesion in the trachea, bronchi, lung and chest, lesions are more cough, chest pain, respiratory effects, severe breathing difficulties, hypoxia, and even respiratory failure and death. Due to air pollution, smoking and other factors, The chronic obstructive pulmonary disease is increasing including chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection the morbidity and mortality of the disease at home and abroad . Therefore, anti-respiratory disease drugs are also more and more attention paid by researchers. Respiratory disease have the symptoms of cough, sputum, hemoptysis, chest pain, shortness of breath and other symptoms of lack of specificity, often clinicians mistaken by people for colds, bronchitis, and severe pneumonia, tuberculosis or lung cancer and other diseases delayed diagnosis; Respiratory tract infection, to be developed to emphysema, pulmonary heart disease, respiratory failure was taken seriously, but it was too late, its pathology and physiological function has been difficult to reverse. As with other systemic diseases, careful and detailed medical history and physical examination are the basis for the diagnosis of respiratory diseases, and should be combined with routine laboratory tests and other special findings to conduct a comprehensive and comprehensive analysis. Currently the most clinical application of anti-respiratory disease drugs have the following four categories: 1. Antihistamines 2. Cough medicine 3. Bronchodilator 4. Expectorant 5. Anti-asthma drugs.
