Tomato top blade abnormalities
Jiyang Vegetable Farmers, Shandong Province Q: My tomato has reached its mid-late stage of growth. Most of the plants have had leaf deformities. How is this going to happen? Shao Hongzhu A: There are many reasons for the deformity of the leaves, such as herbicide damage, point anther phytotoxicity, pests feeding, etc. You can judge through field observation: herbicide phytotoxicity usually spreads from the air outlet to the full shed, usually the top leaf deformity is severe; the point anther is usually inconsistent in the shed, heavy and light, usually from the top One ear appears. In the case of herbicides, the growth regulators can be quickly sprayed to promote the recovery of the growing point and the middle and upper leaves, such as cytokinins, alizarins and so on. When the anther weight is too heavy, the concentration should be reduced immediately, and then the normal photosynthesis of the leaves should be maintained by using functional leaf fertilizers containing total amino acids and seaweed extract or full-fledged foliage fertilizer.
