Description

FIELD OF INVENTION

The present invention relates to new amine derivatives, the processes for the production thereof and insecticides containing the said derivatives as effective compounds.

DESCRIPTION OF RELATED ART

A large number of chemicals, for example, organophosphorus compounds such as parathion and malathion and carbamate compounds such as carbaryl and methomyl, have been developed and put to practical use as insecticides over many years. These insecticides have played a very great role for the improvement of agricultural production. However, in recent years some of these insecticides are regulated on their use because of problems such as environmental pollution due to residue or accumulation, or cause infestation of resistant insect pests as a result of long-term use. Therefore, there is a need to develop new chemicals which have excellent insecticidal characteristics over various types of insect pests including these resistant insect pests and which can be used safely.

The following compound is known as the isomer compound of this invention, which has no insecticidal activity. ##STR2## Further, the following compound is described in U.S. Pat. No. 4,918,088, which has insecticidal activities. ##STR3## The compound however shows no insecticidal activity against lepidopterous insects and green rice leafhopper which are more serious pests on crops, though it shows some activity against cotton aphid.

The purpose of this invention is to provide agricultural chemicals which can be advantageously synthesized industrially, have certain effects and may be applied safely.

The compound of this invention has high insecticidal activity against both lepidopterous and hemipterous insects.

This reaction is carried out in an inactive organic solvent, preferably DMF, THF, benzene acetonitrile, acetone, methylethylketone, in the presence of acid accepter such as potassium carbonate, NaH, triethylamine, between room temperature and the boiling point of the used solvent.

(4) Preparation Method 4: ##STR8## where R.sub.1, R.sub.2, R.sub.3, X and Hal are as defined above. This reaction is carried out in the same manner as that of Preparation Method 3.

This reaction is carried out in an inactive organic solvent, preferably acetonitrile, carbon tetrachloride, dichloroethane, in the presence of nitration reagent such as nitronium tetrafluoroborate, between -20.degree. C. and the boiling point of the used solvent.

After the reaction is completed, an usual after-treatment gives the intended compound. The structure of the compounds of this invention was determined by such means as IR, NMR, MASS, etc. When R.sub.2 is hydrogen in a compound of this invention, tautomers represented by ##STR10## can exist.

The syn-aniti isomers, when Z represents N, and the cis-trans isomers, when Z represents CH, as represented by, ##STR11## can also exist.

The ratio varies depending on e.g. conditions of instrumental analysis.

insect pests such as cutworms, diamondback moth, aphids, leafhoppers and planthoppers. In recent years the decrease of the control effects of organophosphorus and carbamate insecticides, which is caused by the development of resistance to these insecticides, has become serious problem. In such situations, the development of new insecticides which is effective on the resistant pests has been desired. The compounds of this invention possess superior insecticidal activities against not only susceptible strains but also resistant ones.

The insecticides covered by this invention contain as active ingredients one or more types of the compounds as expressed by the general formula (1). These active ingredients, may be used as produced but normally they are used in any of the forms which ordinary agricultural chemicals can take, namely wettable powder, dust, emulsifiable concentrate, suspension concentrates, smoking chemicals, fumigant, granule, or other formulations. For additives and carriers are used soybean flour, wheat flour or other vegetable flours, diatomaceous earth, apatite, gypsum, talc, pyrophyllite, clay or other fine mineral powders, when solid formulations are intended.

When liquid formulations are intended, then for solvents are used kerosene, mineral oil, petroleum, solvent naphtha, xylene, cyclohexane, cyclohexanone, dimethylformamide, dimethylsulfoxide, alcohol, acetone, water, etc. A surface active agent may, if necessary, be added in order to give a homogeneous and suitable formulation. The wettable powders, emulsifiable concentrates, suspension concentrates, etc. thus obtained are diluted with water into suspensions or emulsions of a prescribed concentration, before they are actually sprayed on plants in the field. In the case of dusts or granules, they are directly applied without further processing.

It goes without saying that the compound(s) of this invention is effective even alone, but it can be used by mixing with various types of insecticides, acaricides and fungicides.

Typical examples of acaricides and insecticides which can be used by mixing with the compounds of this invention are described below:

Acaricides (fungicides): chlorobenzilate, chloropropylate, proclonol, bromopropylate, dicofol, dinobuton, binapacryl, chlordimeform, amitraz, propargite, PPPS, benzoximate, hexythiazox, fenbutatin oxide, polynactine, chinomethionat, thioquinox, chlorfenson, tetradifon, phenproxide, avermectins, clofentezine, flubenzimine, fenazaquin, pyridaben, fenproximate, chlorfenethol, thiophanate-methyl, benomyl, thiram, iprobenfos, edifenfos, fthalide, probenazole, isoprothiolane, chorothalonil, captan, polyoxin-B, blasticidin-S, kasugamycin, validamycin, tricyclazole, pyroquilon, phenazine oxide, mepronil, flutolanil, pencycuron, iprodione, hymexazole, metalaxyl, triflumizole, diclomezine, tecloftalam, vinclozolin, procymidone, bitertanol, triadimefon, prochloraz, pyrifenox, fenarimal, fenpropimorph, triforine, metalaxyl, oxycarboxin, pefrazoate, diclomedine, fluazinam, oxadixyl, ethoquinolac, TPTH, propamocarb, fosetyl, dihydrostreptomycin, anilazine, dithianon, diethofencarb.

TEST 1

Efficacy for cotton aphid

30 to 50 insects of cotton aphid per plot were inoculated using a small brush on cucumber leaves which were seeded in pots, 10 cm in diameter, and 10 days old after germination. A day later, wounded insect pests were removed, and a chemical solution, which was prepared in the way that the emulsifiable concentrate described in Example 7 of the above example of insecticide was diluted with water to 125 ppm of compound concentration according to the prescription, was sprayed. The pots were placed in a thermostatic room at temperature of 25.degree. C. and humidity of 65%. The number of survival pests was counted 7 days later and the control efficacy was calculated by comparing with that of untreated plot. The results are shown in Table 2.

TEST 2

Efficacy for green rice leafhopper

Rice seedlings of 7 days old after germination were immersed in a chemical solution, which was prepared in the way that the emulsifiable concentrate described in Example 7 of the above example of insecticide was diluted with water to 125 ppm of compound concentration according to prescription, for 30 seconds. After dried in air, the treated seedlings were placed in test tubes and 10 insects of 3rd-instar larvae of green rice leafhopper resistant to the organophosphorus and carbamate insecticides were inoculated. The tubes were covered with gauze, and placed in a thermostatic room at temperature of 25.degree. C. and humidity of 65%. The mortality was checked 5 days later. The results are shown in Table 3.

TEST 3

Efficacy for rice armyworm

The test compounds were formulated into the wettable powder in the same manner as Example 8. The compounds were diluted with water to 125 ppm. A maize leaf was immersed in the chemical solution for 30 seconds. After air-dried, the treated leaf was placed in a petri dish and five 3rd-instar larvae of rice armyworm were inoculated. The petri dishes were covered with glass lids, and placed in a thermostatic room at 25.degree. C. and 65% relative humidity. The mortality was checked 5 days later. Two replications were conducted in the each test. The results are shown in Table 4.
