Use of compounds in conjunction with fertilizers was written by Anonymous. And the article was included in Research Disclosure in 1975.Electric Literature of C8H6O2 This article mentions the following:
Compounds of the formula I (where R1 to R4 may be the same or different alkyl groups) are used in conjunction with fast or slow acting fertilizers to retard plant growth. Thus, I (R1 = R2 = R4 = Me; R3 = Et [26225-79-6]) was applied either at the same time or 3-4 weeks subsequent to the application of solid or liquid form fertilizers. When applied as a mixture with a slow-release fertilizer the preferred proportion was 15-60 parts by weight of N and 1-4 parts I. In the experiment, the researchers used many compounds, for example, Benzofuran-5-ol (cas: 13196-10-6Electric Literature of C8H6O2).
Benzofuran-5-ol (cas: 13196-10-6) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Electric Literature of C8H6O2
