Solarium spp.

Diclosulam is registered in the United States and in Latin America for use in peanuts and soybeans. Applications can be made preplant surface, preplant incorporated and preemergence at rates of 17.5-26 g-a.i. ha for the control of numerous broadleaf weed species. Diclosulam does not provide control of annual and perennial grass weeds or certain broadleaf weeds such as Solarium spp. 

Table 7.3 Steroidal alkaloids (alkamines) alphabetically listed within the different structural types For 41 out of altogether 115 compounds from Solarium spp. (113 compounds), Lycianthes biflora, and Saracha punctata (one compound each) at least one corresponding glycoalktiloid was found and structurally elucidated, i.e., for 36% of the alkamines also corresponding glycosides are known (continued)...

Brassica oleraeea (Brassicaceae) Robinia pseudacacia (Fabaceae), Mosla dianthera (Lamiacae), Moms spp. (Moraceae), Aloe arborescens (Liliaceae), Solarium tuberosum (Solanaceae), Vitis vinifera (Vitaceae) (wine) Musa acuminata, M. paridasiaca (banana) (Musaceae) [fruit]... 

A sesquiterpene phytoalexin, C17H26O4, Mr 294.39, oil, [ain -35.9° (CHCI3) formed, together with rish-itin and many other components (including vetispi-ranes), by potatoes Solarium tuberosum) after infection by the putrefactive bacterium Erwinia carotovora. Deacetylation furnishes phytuberol, C,5H240j, Mr 252.35, oil. P. can also be isolated from the culture medium of potato cell cultures after elicitation with Phy-tophthora infestans. Some sorts of tobacco Nicotiana tabacum) produce P. after infection with various Pseudomonas spp. or the tobacco mosaic virus pretreatment with a cellulase shows the same effect. 

C30H50O M 426.724 (3fi,da,5a,24Z)-form [474-40-8] aj-Sitosterol. Citrostadienol Constit. of Ulmus rubra. Solarium tuberum, Betula verucosa and Populus spp. Found in grapefruit and orange essential oils. Cryst. (Et20/EtOH). Mp 162-164 . [ ]d +24 (c, 1 in CHCI3). 

A recent study by Pospisil (197) showed that tannin may be used as an exogenous antifeedant factor. In this study, Colorado potato beetle larvae refused to eat potato Solarium tuberosum) leaves treated topically with tannic acid solution. In contrast, the larvae of Heliothis spp. exhibited attenuated growth on, but not antifeedant behavior toward a diet containing condensed tannin from Gossypium...
