The first method of prevention and treatment improves the moisture and keeps the leaves dry(104 cell seed starting trays). After the germination is unearthed in the spring of the year, it is normally managed. The soil after flowering should be kept in a thousand or so, in order to facilitate the expansion of new bulbs and the formation and growth of the ball. Most of the diseased leaves, the initial leaf surface will produce round dark brown spots(large plastic terracotta pots), the spots gradually spread and eventually lead to the decay of the blue plant, which is a kind of fungal disease, mostly occurs in the low temperature and humidity and poor ventilation in autumn and winter.(black 3 gallon plastic nursery pots for sale)
Such diseases begin more than internal tissue reproduction, and then spread over the surface of the foliage and the body of the plant(gallon pot). In the cold weather, only a small amount of water is poured, the ambient temperature is raised and ventilation is maintained, and the moist moisture is stagnated on the plant body. Leaf blight begins to change color at the tip of the leaf at the beginning, and then gradually spreads to the whole leaf and the whole plant(105 cell seed starter trays). The whole orchid is dark brown, and the damaged orchid strain is hard to die. This type of lesion is also caused by excessive humidity, and attention should be paid to humidity control.
Keep the soil moist, but there should be no water(105 cell plastic propagation tray wholesale price). The scale insects are mainly parasitic on the leaves, sheaths and false bulbs of orchids, soaking nutrients. When severe, the leaves are yellowed and withered. It occurs mostly in high-humidity, poorly-ventilated and sun-poor cultivation sites. This kind of pests will secrete honeydew, induce soot, affect plant growth and ornamental value(plastic plant pots wholesale suppliers). When a small amount occurs, use a soft brush to remove the eggs, or cut off the parts and remove them.
(black 3 gallon plastic nursery pots for sale)Usually, ladybugs are natural enemies of scale insects, which can prey on a large number of scale insects, thereby inhibiting their occurrence(seed starting trays). When the scale insects occur more, spray 50% of the speed-killing emulsion l000 times solution or 50% marathon emulsion 800 times solution, spray once every 7 to 10 days, and spray 3 times continuously(40 cell seed starting trays). Aphids are mainly harmful in spring and early summer, sucking young leaves, young shoots and developing flowering buds, flower sap and nutrients, leaves and spikes deformed, twisted, and stunted.
Use a sucking mouthpart to penetrate the pores of the orchid to cause soot or other fungal diseases(plastic plant trays wholesale). Spray with omethoate or pyrethrin 1000 times. Natural enemies such as red-spotted ladybug, Japanese square head, and red ring ladybug have a good effect in preying on aphids. Whiteflies usually cluster on parasitic plants, and in severe cases, the entire leaf, leaf sheath and pseudobulb are covered with whitefly(50 cell plastic propagation tray wholesale price). Its fertility is strong and can cause the leaves of orchids to dry out.(black 3 gallon plastic nursery pots for sale)
Finally, the pathogen of tulip pests and diseases can be carried by the bulbs, and can also be carried by the soil to infect the bulbs(square grow pots). The secreted honeydew will attract the ants, spray once every 7 to 10 days, and spray three times in a row. However, the cultivation of Phalaenopsis is more difficult, the pests and diseases are more, and the resistance of Phalaenopsis is weaker. Therefore, it is necessary to pay special attention to the above(20 cell seed starting trays). Some of the common pests and diseases in the cultivation of Phalaenopsis, and the corresponding control techniques, I hope to help everyone.
