Plant cultivation materials, which have the liquid retentivity and the liquid transitivity, which provide the best environment for plants respiration, which comprises polyesters, natural pulps and/or synthetic pulps such as polyolefin pulps, from which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want, and which provide the cultivation environment to accelerate the plant growth, and the plant cultivation methods by using the materials can be provided.

Plant cultivation material and plant cultivation method using the material

A fungicide can be provided by using, as an active ingredient, a diamine derivative of the following general formula (1): 

Diamine derivatives, process for producing the diamine derivatives, and fungicides containing the diamine derivatives as an active ingredient

A novel nitroisourea derivative and a process for producing the same, which is an important intermediate for the production of a nitroguanidine derivative having an insecticidal activity, and a process for producing a nitroguanidine derivative having an insecticidal activity using the nitroisourea derivative. The process for producing a nitroguanidine derivative represented by formula (1), effective as an insecticide is shown by reaction scheme (2): ##STR1## wherein R.sub.1 represents an alkyl group having from 1 to 4 carbon atoms or a benzyl group; R.sub.2 represents an alkyl group having from 1 to 4 carbon atoms; R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each independently represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; and Q represents a 5-membered or 6-membered heterocyclic ring having at least one of the following: a nitrogen atom, an oxygen atom or a sulfur atom, one of the hydrogen atoms being substitutable with a halogen atom.

Nitroisourea derivative

A tetrahydrofuran-compound is disclosed herein which is represented by the formula (1) ##STR1## wherein each of X.sub.1 and X.sub.2 is a hydrogen atom or a methyl group, Y is a hydrogen atom or a carbonyl group substituted by a lower alkyl group (Y') having 1 to 4 carbon atoms, i.e., an acyl group (--COY'), and

Insecticidal tetrahydrofuran-compound

The present invention relates to novel (tetrahydro-3-furanyl)methylamino derivatives of the following formula (1): ##STR1## wherein the variables are defined in the specification, which are useful as insecticides.

Intermediate for furanyl insecticide

Furanyl insecticide

The present invention relates to novel N-vinylimidazolidine derivatives of the following formula (1), a process for producing them, an insecticide containing the derivatives as an effective ingredient, and novelintermediates. The derivatives (1) are useful as agricultural chemicals (particularly, as insecticides) in the fields of agriculture, and the intermediates are useful in various industrial fields, especially as intermediates for agricultural chemicals. ##STR1## where R.sup.1, R.sup.2, Z are as defined in the specification.
