First, the incidence conditions
Strawberry gray mold is a disease of low temperature and high humidity. The suitable onset temperature is 18--25°C, the highest is 32°C, and the lowest is 4°C. The optimum relative humidity is 92-95% or the water on the plant surface is suitable for onset.
Second, prevention and control measures
According to the occurrence characteristics of this disease, do a good job in prevention and control measures:
1. It is particularly important to strengthen the discharge of moisture, especially in the season where there is more rain, and there can be no accumulation of water in the fields.
2, rational close planting, enhance field permeability, reduce the humidity in the field.
3, clean the garden, timely removal of diseased leaves out of the field buried deep, reduce infection.
4. Induce strong protection and strengthen the strawberry's self-resistance to disease resistance. Use the "too resistant + bi-protection" spray to enhance the disease resistance of the strawberry.
5. Control of pesticide application in the early stage of the disease can be controlled by alternate use of pyrimethanil, acetaminophen, and procymidone.
Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
