Vegetable diseases in greenhouses should be remedy for the disease. The vegetables in greenhouses are diverse in variety and cultivation methods. The farming system is complex, the temperature is high, the humidity is high, the diseases are easy to occur, and there are many types of pests and diseases.
Some vegetable farmers spray pesticides on various vegetable diseases, whether they are fungal diseases, bacterial diseases, viral diseases or physiological diseases, when they see changes in vegetable leaves and fruit tips; for all kinds of vegetable pests, whether by mites It is caused by aphids, and regardless of the medicine used, it can not cure the insects. This is not the right approach.
Each pest has its unique habits and harmful characteristics. For example, powdery mildew is easy to invade the young part of melon, black spot is easy to infect from the lower leaves, and the mites are concentrated on the back of the leaves to absorb vegetable juice. Most pesticides that control pests and diseases are particularly specific, often targeting diseases or pests caused by one or a certain type of pathogen, and not effective against other diseases or insect pests. Therefore, it is necessary to apply drugs due to illness and insects when applying drugs.
When individual vegetable farmers see pests in the shed, they want to completely eliminate them. In fact, they are completely unnecessary. From the perspective of economics, pests in the shed do not need to be controlled as long as they do not exceed the control indicators, otherwise it may reduce the ratio of output to investment, which is not worth the loss.
