Whether to give the orchid medicine at noon or in the afternoon

In order to prevent and control the occurrence of crop diseases and pests, improve the quality of vegetables and fruits, and increase economic benefits, spraying has become the best way, but the pesticide application time of different crops in different seasons and different growth stages is different. For example, cucumbers in greenhouses, in the high temperature season, choose a sunny day after about 9 o'clock in the morning and after 4 o'clock in the afternoon, the effect of spraying is better, because after 9 o'clock in the morning, the dew has dried, the temperature is not too high, and the activity of pests and diseases is vigorous, so the effect of spraying is the best at this time; After 4 p.m., nocturnal pests are active, and spraying at this time can effectively kill pests.

It should be noted that spraying should not be done at noon, because at noon due to the strong light and high temperature, the pests will hide in the backlight, and the high temperature will also lead to the decomposition of the drug effect.

In winter and spring, generally between two and a half to three and a half in the afternoon, in winter and spring, the temperature in the shed is low, and if you spray at noon, it will reduce the temperature and affect photosynthesis, so it is not suitable to spray in the morning. In addition, under the hot weather, the crop growth activity is vigorous, the stomata on the leaves are expanded, and the pesticide damage is easy to soak into the crop, which may lead to crop damage.

Orchids are usually placed indoors, and spraying is different from outdoor plants (such as morning dew will reduce the concentration of pesticides, etc.), so you don't need to consider the time problem, because the indoor environmental factors change little.

Use as directed on the pouch of the medicine.

For the safety of the applicator, it is generally recommended to administer the drug before 10 a.m. and after 4 p.m.

Fertilizing vegetables should be done in the afternoon; Spraying should be done before 11 a.m. and after 4 p.m.

Orchid fertilization and spraying should be done with caution. Generally, for weak seedlings and diseased seedlings, it is mainly cleaned up, and fertilization is counterproductive, and even leads to plant death. Orchids should not be fertilized in the following situations:

Orchids should not be fertilized in early spring, fertilized at high temperature in midsummer, fertilized in winter, fertilized at noon, fertilized when new orchids are just potted, orchids are not robust and cannot be fertilized, new shoots are not grown and should not be fertilized, flower buds are not full and should not be fertilized, and the planting material is too dry or too wet to fertilize.

In short, orchid cultivation should be done with little or no fertilization. For ordinary seedlings, the normal growth of orchids can be met by applying thin fertilizer up to 5 to 6 times a year.

The afternoon is most suitable because there is no fog and water. Spraying insects is the easiest to kill.

Between 9 a.m. and 4 p.m., it is best for spraying crops.

Yes, under normal circumstances, it is better to spray carbendazim for sterilization and disinfection for about a month The leaves are often sprayed with potassium dihydrogen phosphate, and the leaves are greener and brighter.

The most suitable time is: after the dew dries in the morning to 12 o'clock, after 3 o'clock in the afternoon to avoid high temperature to prevent the occurrence of pesticide damage.

It is better in the morning, before eight o'clock in the morning, the sun is stronger during the day, the temperature is higher, the tree is not easy to absorb, because of the temperature, it is easy for the fruit tree to die!!

8-10 am and 5-7 pm are optimal.

How to properly use fungicides for orchid maintenance in summer?

In general, potassium permanganate is better, spraying carbendazim or methyl tobuzine is better for sterilization and disinfection, orchid plantar planting is better, watering is controlled, and the roots are easy to rot when the humidity is high.
