| While vigorous vines may be able to recover from a single defoliation, repeated defoliation can weaken the vine to the point of death. |
|
| However, the genetics of a naturally early leaf defoliation trait in wild cotton was not studied. |
|
| The distinctive, compound palmate leaves typically drop with heat or drought, but defoliation may be less with more shade and water. |
|
| We evaluated the costs of leaf height and defoliation in this plant by conducting a replicated field experiment in a forested landscape. |
|
| In older wood, epicormic shoots often result from severe defoliation or radical pruning. |
|
| Since deciduous plants regrow new leaves each year, the defoliation caused by bagworm feeding is usually not serious. |
|
| Treatment may be warranted if the insects are actively feeding and defoliation is expected to increase. |
|
| Botanical humans are at war with a cervine insurgency that has greater defoliation power than a squadron-load of Agent Orange. |
|
| Slug injury to corn may occur before emergence due to feeding activity on the seeds in the furrow or to severe defoliation soon after emergence. |
|
| Unlike Japanese larch and white pine, defoliated bear oak seedlings showed very little response to partial defoliation. |
|
| The apple small ermine moth causes more or less serious defoliation at the tips of branches of apple trees. |
|
| Because of the slowness of growth it is long to recover from a defoliation caused by the cold first of the winter. |
|
| It was also linked to S content in foliage and subsequently with defoliation. |
|
| Repeated defoliation results in a decrease in growth increment and death of shoots and twigs. |
|
| Because of the late colonization and the resulting low beetle density, crop defoliation was never high. |
|
| The quiescent period of the vine from defoliation in autumn until budding in the spring. |
|
| The effects of defoliation depend in part on the timing of defoliation. |
|
| Since 2000 the incidence of these diseases has increased significantly and caused severe defoliation in both sprout and fruiting fields. |
|
| High variation in one spruce stand in the Czech Republic could be explained largely by the high stand density and exceptional defoliation. |
|
| Percentage of trees in different defoliation classes for main tree species. |
|
|
|
| The results of the 1990-survey indicate that a significant part of the forests in the Community show signs of defoliation or discolouration. |
|
| Both these diseases were widespread among tussock moth caterpillars in areas of moderate to severe defoliation in Nova Scotia. |
|
| In the case of some insect infestations, particularly spruce budworm and gypsy moth, repeated defoliation can cause the death of trees over a large area of forest. |
|
| Because the Sesbania species have pinnately compound leaves, for defoliation the central rachis of the leaf was cut once halfway along its length. |
|
| Areas reported as defoliated may include patches that differ in the degree of defoliation severity. |
|
| Generalized foliar necrosis, caused by coalescence of several lesions, can result in defoliation. |
|
| The concentration of both glutamine and asparagine, the most abundant of the specific amino acids, declined rapidly during phase 1 after defoliation. |
|
| Above-ground symptoms include chlorosis and reddening of the leaves, small leaves, defoliation, branch dieback, death of entire canes, stunting, and death of the entire bush. |
|
| These buds may be induced to flush by defoliation or unusual weather patterns. |
|
| While some plants from grassland or desert habitats undergo overcompensatory growth in response to defoliation, it is unlikely that perennial forest herbs can do so. |
|
| The defoliation caused by the large aspen tortrix does not affect tree survival since it occurs early enough in the summer season to allow the trees to produce new foliage. |
|
| For mature asparagus, sprays should begin July 1, after crop has been harvested, and continue at 3-4 week intervals until defoliation in October. |
|
| Cotton is a perennial crop in the tropics, and without defoliation or freezing, the plant will continue to grow. |
|
| Severe attacks of D. perspectalis can lead to defoliation and therefore completely disfigure Buxus plants which in many cases are grown for ornamental purposes. |
|
| In 2000 almost one-third of Polish tree stands still had defoliation of more than 25 percent, exceeding the levels for many of Poland's European neighbours. |
|
| Woodrats are usually common within their ranges, but Allegheny woodrat populations are declining, possibly because of forest defoliation by gypsy moths and infestation by parasites. |
|
| More visible damage, such as defoliation, may show up later. |
|
| Thus no defoliation was forecast for 2006 and none was detected. |
|
| Figure 1 shows that Ultraferro behaved in a similar manner in terms of efficiency, evaluated as a percentage of iron-induced chlorosis and defoliation, compared with the standard chelate product. |
|
| Apple scab generally does not kill the trees but it can cause defoliation, which will weaken the tree and influence its survival during winter conditions. |
|
|
|
| Two-thirds of the defoliation was caused by the elm spanworm, a leaf-eating caterpillar which attacks primarily beech, elm and maple trees. |
|
| Local plants have already had to deal with defoliation from forest tent caterpillars and gypsy moths. |
|
| Some of the leaves may be removed from below tomato trusses as the fruit starts to ripen but don't overdo defoliation because the leaves manufacture food for the plant. |
|
| Signs are extensive defoliation of trees, caterpillars with blue and red dots on their bodies feeding on leaves or on branches, and buff-colored egg masses on tree trunks. |
|
| By the end of October the defoliation process becomes evident. |
|
| Uzbekistan proposed Kyrgyzstan to acquire chemical remedies for agriculture, in particular magnesium chlorate defoliant for defoliation of cotton. |
|
| Leaves defoliation resulting from human consumption of leaves and also pest defoliators coupled with poor management practices had led to low okra productivity. |
|
| Surveys across the state indicate gypsy moth populations are increasing and have the potential to cause defoliation in 2015, especially in eastern Pennsylvania. |
|
| Defoliation induced an increase in the number of resin droplets in the fertilized saplings. |
|
| Defoliation is, of course, a natural process and happens at the end of each growing season in the autumn. |
|
| Defoliation by lepidoptera can induce cyanogenesis in some plants resulting in cyanide levels high enough to kill cattle. |

| Remote-Sensing and Tree-Ring Based Characterization of Forest Defoliation and Growth Loss due to the Mediterranean Pine Processionary Moth. |
