| During their propagative stage they form fruiting bodies and sporangia, which bear walled spores like typical fungi. |
|
| Thus, the trees and propagative budwood are symptomless carriers of the bacteria during this period. |
|
| Roots may also be structurally modified as propagative and food-storage organs. |
|
| Long-distance dissemination of either phytoplasma could be through infected propagative material. |
|
| The population is composed of males, females and four larval stages in this propagative stage of rapid multiplication. |
|
| It can be carried latently in potato tubers and other propagative plant materials such as geranium cuttings. |
|
| Long-distance spread of mal secco occurs through infected propagative material and plants. |
|
| The principal vector is the leafhopper Macrosteles fascifrons, in which the phytoplasmas are propagative. |
|
| About 350 greenhouse floriculture growers in Ontario produce an estimated 34 million square feet of cut flowers, potted plants, annual bedding plants and propagative plant material. |
|
| Direct application of dry or wet heat is used to obtain seeds, bulbs, other propagative materials, and even entire plants free of viruses, nematodes, and other pathogens. |
|
| Eradicants are designed to kill a pathogen that may be present in the soil, on the seeds, or on vegetative propagative organs, such as bulbs, corms, and tubers. |
|
| Order of the Walloon Government of April 21, 2005, on the marketing of propagative material of fruit crops and fruit crops for the production of fruit. |
|
| The Plant Health program's internal reports indicate that some 513 million plants are imported each year from the United States and 43 million propagative plants from 17 other countries. |
|
| Revised to regulate the importation of Ribes spp. propagative material originating from all areas where black currant reversion virus is know to occur. |
|
| In the propagative life cycle, fourth-stage larvae of the nematodes are transmitted to recently dead or dying trees during oviposition by the female vector. |
|
| Order of the Flemish Government of March 18, 2005, on the marketing of propagative material and seedlings of vegetables, with the exception of vegetable seed. |
|
| For the propagative modes, the problem is reduced to a rational approximation on an interval of the negative real semiaxis, similarly to in the isotropic case. |
