Neem oil is a natural repelent and fungicide that can be used to prevent and treat various diseases and pests in asparagus. Neem oil is obtained from the seeds of neem (Azadirachta indica), an Indian tree traditionally used in Ayurvedic medicine.
Repelent action - neem oil acts as a natural repelent that can help fight pests such as asparagus fly and asparagus wasp. Neem oil interferes with the feeding and development of insects, which can reduce their population.
Fungicidal action - neem oil also acts as a natural fungicide that can help prevent and treat diseases such as gray mold and bacterial blight. Neem oil prevents the development of fungi and bacteria by inhibiting their growth and reproduction.
Neem oil should be diluted in water before use. A concentration of 0,5% to 1% neem oil with emulgator in water is usually used. This means that you will add 0,5 to 1 ml of neem oil to 100 ml of water.
To use neem oil, it should be diluted in water according to package directions and applied to the leaves and stems of plants using a spray. It is important to apply neem oil early in the morning or late in the evening when the temperature is lower to avoid leaf burn. Neem oil should also be applied regularly, every few weeks, to ensure effectiveness.
