Marigold pest control recommendations
The middle and late period of marigold production is the key period for the production of crops, and also the multiple and prosperous period of diseases and insect pests. Among them, the onset of brown spot disease is rapid, spread rapidly, and the harm is heavy. When it is severe, it can be contiguous and dead in a large area for 7 to 10 days. It should be prevented as soon as possible. 1. Strengthen the management of farmland. Clean the garden, remove the water in the field, eradicate the weeds, improve the ventilation and light transmission conditions, increase the permeability, and reduce the humidity in the field. 2. Remove diseased foliage. For early plants with viral diseases and root rots that do not normally flower and die, roots were removed and buried deep outside the field. Severe patches of brown spot disease were combined. The lower diseased leaves and leaves were removed and buried deeply by cultivating and weeding. 3. Chemical control: no diseased plots, 70% mango Mn-Zn wettable powder 100 g watered 40 to 50 kg spray; spot plots, acres selected 43% 43% tebuconazole suspension (or 40% azoxystrobin suspension 20 grams) watered 30 to 40 kg spray; re-application of 45% Prochlorin aqueous emulsion 40 grams of 40 grams +43% tebuconazole suspension 15 grams, watered 30 kg spray. For the first time after the first field application, the second field application was performed for the first time. The severe field block should be applied for the third time after the second time. The spread of brown spot disease can be effectively controlled. 4. Precautions: 1. Chemical control should be sprayed immediately after the flowers are collected and concentrated. Spraying should be based on stems and leaves as much as possible. After spraying for 7 days, squat should be harvested. Spraying should be uniform when spraying. The leaves are to be sprayed. 2. In case of continuous rainfall, it shall be rushed to apply pesticides timely during the rainy season, and the rain shall be sprayed within 4 hours after spraying.
