Disclosed herein are copper based fungicidal and bactericidal compositions having enhanced activity against fungi and bacteria, methods of using such compositions as well as methods for increasing the effectiveness of the copper based fungicidal and/or bactericidal compounds employed in such compositions. An aggregation inhibiting salt is included within these compositions to prevent aggregate and/or sediment formation upon the addition of Fe.sup.+3 to the composition.

Methods for preventing precipitation of copper from copper based

Disclosed herein are copper based fungicidal and bactericidal compositions having enhanced activity against fungi and bacteria, methods of using such compositions as well as methods for increasing the effectiveness of the copper based fungicidal and/or bactericidal compounds employed in such compositions.

Iron enhancement of copper based fungicidal and bactericidal compositions

Methods and compositions for enhancing the yield of root crops, such as potatoes, sugar beets, radishes and the like, comprise treating the roots, plants, seeds, seed pieces, or soil in which they are to be planted, with a root crop growth promotant bacteria of the genus Pseudomonas.

Root crop growth promotants

DNA sequences encoding for plant growth promotant activity have been isolated and introduced into microorganisms. The modified organisms are able to confer plant growth promotant activity analogous to that of the DNA source host. Such modified hosts find use in promoting the growth of root crops by innoculating the rhizosphere with such microorganisms. E. coli HB101 (pS FL-1) was deposited at the A.T.C.C. on Oct. 8, 1982, and granted accession no. 39206.
