Various phytotoxicities

Plusieurs plantules de laitue montrent quelques feuilles dont le limbe est plus dentelé et découpé. <b>Phytotoxicité</b>
Leaf deformations are sometimes very marked. The cotyledons, but especially the young leaves of these few seedlings present thicker tissues; the blade is strongly coiled and tormented. <b> Phytotoxicity </b>
This salad plant did not appreciate the effects of Mocap; the majority of its leaves, especially the youngest, turn brown, wilt and begin to necrose. <b> Phytotoxicity </b>
All the salads, slightly chlorotic, show a more upright habit and several rolled leaves; these are symptoms of phytotoxicity. <b> General distribution </b>
The growth of young leaves can be greatly reduced or even blocked by <b> phytotoxicity </b>. This is the case with this young salad, some of whose leaves are also strongly deformed.
We find the same situation in the presence of a <b> phytotoxicity </b> which, too, induced the blockage and the deformation of the leaves of the heart of this young salad.
The leaves in the heart of this lettuce are smaller than normal and chlorotic. <b> Phytotoxicity </b>
A herbicide, with particularly distorting effects, gave this salad a crumpled appearance. <b> Phytotoxicity </b>
Phytotoxicite3
On all salads (as is often the case with phytotoxicity), we can distinguish on several leaves the presence of chlorotic changes at the edge of the blade. <b> Phytotoxicity (fungicide) </b>
On this young lettuce leaf, there is a yellowing of the blade starting from the veins. <b> Phytotoxicity </b>
Yellowing of the leaf blade beginning from the veins. <b> Phytotoxicity </b>
Small chlorotic spots starting on or near the veins. <b> Phytotoxicity </b>
Even yellowing of the tips of old leaves. <b> Phytotoxicity </b>
A multitude of small beige to brown alterations, of various shapes, cover this lettuce leaf. These appeared following a fungicide treatment carried out under bad conditions. <b> Phytotoxicity </b>
A few chlorotic lesions which quickly become necrotic develop near the veins of this lettuce leaf. <b> Phytotoxicity </b>
Spray from a herbicide fell more or less regularly on this young salad. Several irregularities, brown and interveinal, gradually appear on one of its leaves. <b> Phytotoxicity </b>
Dark brown to brown interveinal spots affect the most exposed portions of the blade. <b> Phytotoxicity </b>
After having received projections of Gramoxone during a herbicide treatment, this batavia reveals some more or less extensive leaf necrosis. It should be noted that some of them are located at the edge of the limbus where product accumulations may have occurred. <b> Phytotoxicity </b>
These brown necrotic spots, confluent in places, appeared following treatment with a herbicide to destroy weeds growing between the rows. <b> Phytotoxicity </b>
Phytotoxicite4
The outermost leaves gradually turned yellow and dried out. <b> Phytotoxicity </b>
Several completely dried leaves materialize the effects of a mixture of pesticides rather poorly supported by one of the 2 varieties of oak leaf lettuce cultivated (located on the right). <b> Phytotoxicity </b>
