Abstract
Novel capsule preparations for the treatment of plants, which preparations are composed of A) a capsule shell comprising water-soluble polyoxyethylene having a number average molecular weight of 100,000 or more, at least one plasticizer and optionally, one or more additives, and B) a filling comprising at least one biologically active compound and optionally, one or more auxiliaries, and a method for administering biologically active compounds to plants, such as trees and shrubs, by inserting the novel capsule preparations into the plants.
Claims3
A method for administering a biologically active compound to a plant, said method comprising inserting into said plant a capsule preparation alone comprising:
- A) a capsule shell consisting essentially of:
- i) water-soluble polyoxyethylene having an average molecular weight between 100,000 and 8,000,000;
- ii) at least one plasticizer;
- and
- iii) optionally, one or more additives;
- and
- B) a filling comprising:
- i) at least one insecticidal or nematocidal compound selected from the group consisting of:
- a) O,O-dimethyl O-3-methyl-4-(methylsulfinyl)phenylphosphorothioate,
- b) trans-1,4,5,6-tetrahydro-1-methyl-2-[2-(3-methyl-2-thienyl)-vinyl]-pyrimid ine tartrate,
- c) (-)-(S) -2,3,5,6-tetrahydro-2-phenylimida[2,1-b]thiazole hydrochloride,
- d) 1-(6-chloro-3-pyridylmmethyl)-N-nitro-imidazolidin-2-ylideneamine,
- e) (RS)-S-sec-butyl O-ethyl 2oxo-1,3-thlazolidin-3-yl-phosphorothioate,
- f) O-ethyl S,S-diisopropyl phosphorodithioate,
- g) N-[(6-chloro-3-pyridyl)-methyl]-N-cyano-N-methyl acetamidine,
- h) N-[(6-chloro-3-pyridyl)-methyl]-N-ethyl-N-methyl-2-nitro-1,1-ethanediamine
- i) N-(2-chloro-5-thiazolylmethyl)-3-methyl-2-nitro-guanidine;
- and
- j) 1-(2-chloro-5-thiazolylmethyl)-3,5-dimethyl-2-nitro-iminohexahydro-1,3,5-t riazine;
- and
- ii) optionally, one or more auxiliaries.
