Ved å anvende det egnede 2-alkyl-3-hydroxy-l,4-naftho- kinon og det .egnede syreklorid eller -anhydrid vil de i tabell I angitte forbindelser kunne fremstilles på lignende måte av fagmannen ved hjelp av den i eksempel 1 og 2 beskrevne fremgangsmåte . By using the suitable 2-alkyl-3-hydroxy-1,4-naphthoquinone and the suitable acid chloride or anhydride, the compounds listed in Table I can be prepared in a similar way by the person skilled in the art using the method in example 1 and 2 described procedure.
Forbindelsene med formel I er nyttige som middicider og kan anvendes for beskyttelse av planter og dyr mot beskadigelse forårsaket av disse skadedyr. Nærmere bestemt kan frukter, feltvekster, grønnsaker, prydbusker, fugler og andre varmblodige dyr omfattende mennesket også beskyttes. The compounds of formula I are useful as midcidides and can be used for the protection of plants and animals against damage caused by these pests. More specifically, fruits, field crops, vegetables, ornamental shrubs, birds and other warm-blooded animals including humans can also be protected.
Middene kommer i kontakt med forbindelsene med formel The mites come into contact with the compounds with formula
I i form av en direkte dusj eller ved at de spaserer over over-flater som er blitt behandlet med en hvilken som helst av forbindelsene med formel I, og de blir hurtig irritert og forlater området eller drepes hvis de er blitt utsatt for en effektiv dose. Selv om de fleste ..planter eller dyr er istand til å >tåle til-stedeværelsen av et meget lite antall midd uten tilsynelatende uheldig virkning, er disse skadedyrs formeringsevne enorm. -Middpopulasjoner dannes generelt hurtig og vil lett vanskelig-gjøre parasitt- og skadedyrkontroll. Dyrkere som merker en hurtig dannelse av midder, må ta øyeblikkelig aksjon for å hindre beskadigelse av økonomisk verdifulle vekster. Det foreligger derfor behov for en fremgangsmåte for øyeblikkelig reduksjon av middansamlinger og for derved å hindre at verdifulle planter eller dyr beskadiges. I in the form of a direct shower or by walking over surfaces treated with any of the compounds of formula I, and they are quickly irritated and leave the area or are killed if exposed to an effective dose . Although most ..plants or animals are able to tolerate the presence of a very small number of mites without apparent ill effect, the reproductive capacity of these pests is enormous. -Mite populations generally form quickly and will easily make parasite and pest control difficult. Growers who notice a rapid buildup of mites must take immediate action to prevent damage to economically valuable crops. There is therefore a need for a method for immediate reduction of mite accumulations and thereby preventing valuable plants or animals from being damaged.
På lignende måte er forbindelsene med formelen I også nyttige som bladlusbekjempelsesmidler og kan brukes for å beskytte frukter, feltvekster og grønnsaker, prydbusker og andre planter fra angrep av bladlus. Når forbindelsene tilføres til bladlus eller til stedet for bladlusangrep, vil disse skådedyr drepes eller drives bort fra plantene. Similarly, the compounds of formula I are also useful as aphid control agents and can be used to protect fruits, field crops and vegetables, ornamental shrubs and other plants from attack by aphids. When the compounds are applied to aphids or to the site of aphid infestation, these pests will be killed or driven away from the plants.
Midlene ifølge oppfinnelsen gjør det mulig hurtig å kontrollere disse skadedyr ved at midd eller bladlusene bringes i kontakt med en effektiv konsentrasjon av en eller flere forbindelser med formel I. Meget små mengder av forbindelser med formelen I er f.eks. nødvendige for å erholde en antimidd- eller antibladlusvirkning. Dessuten vaskes forbindelsene ikke lett bort fra bladene på grunn av regn. De har ingen uheldig innvirk-ning på marihøne som er viktige spisere av midd og bladlus, og forbindelsene brytes hurtig ned i omgivelsene. Forbindelsene er også effektive mot fosforresistente stammer av midd. The agents according to the invention make it possible to quickly control these pests by bringing mites or aphids into contact with an effective concentration of one or more compounds of formula I. Very small amounts of compounds of formula I are e.g. necessary to obtain an anti-mite or anti-aphid effect. Also, the compounds are not easily washed off the leaves by rain. They have no adverse effect on ladybirds, which are important eaters of mites and aphids, and the compounds break down quickly in the environment. The compounds are also effective against phosphorus-resistant strains of mites.
Den nødvendige mengde forbindelse for å oppnå en antimidd- eller antibladlusvirkning, vil variere avhengig av den spesielle situasjon. Blandt dé variable som må vurderes ved bestemmelse om mengden av kjemikalier som skal. anvendes, er selve forbindelsen, den ^spesielle mi,dd eller bladlus som skal bekjempes, værbetingelser, veksttypen, vekstens utviklingstrinn, det påsprøytede volum, populasjonstrykk og tiden mellom påførin-gene. For beskyttelse av planter kan oppløsninger eller suspensjoner inneholdende så lite som 5 ppm aktiv bestanddel i en sprøytepppløsning vise seg effektiv under visse betingelser. The amount of compound required to achieve an anti-mite or anti-aphid effect will vary depending on the particular situation. Among the variables that must be considered when determining the amount of chemicals that must. used, is the compound itself, the special agent or aphid to be controlled, weather conditions, the type of growth, the stage of development of the growth, the volume sprayed, population pressure and the time between applications. For the protection of plants, solutions or suspensions containing as little as 5 ppm of active ingredient in a spray solution may prove effective under certain conditions.
For feltbruk hvor store volum anvendes, er imidlertid vandige sprøytepréparater inneholdende 40 - 4 000 ppm aktiv bestanddel vanligvis tilstrekkelig. Det foretrekkes å anvende suspensjoner inneholdende 80 - 1000 ppm, helst 150 - 500 ppm. På arealbasis er vanligvis 0,03 - 15 kg aktiv bestanddel pr. hektar aksepter-bart, fortrinnsvis 0,0 6 - 8 kg, og helst 0,1-4 kg. Ved anvendelse i en frukthave fortsettes sprøytingen til sprøyteprepa-ratét begynner å dryppe av. However, for field use where large volumes are used, aqueous spray preparations containing 40 - 4,000 ppm active ingredient are usually sufficient. It is preferred to use suspensions containing 80 - 1000 ppm, preferably 150 - 500 ppm. On an area basis, 0.03 - 15 kg of active ingredient per hectare acceptable, preferably 0.06-8 kg, and most preferably 0.1-4 kg. When used in an orchard, the spraying is continued until the spray preparation starts to drip off.
Det kan være ønsket eller gunstig å blande forbindelsene med andre landbrukspesticider eller -tilsetningsmidler. Slike blandinger øker ofte virkningen ved bekjempelse av midd og utvider bekjempelsesomfanget til å gjelde andre pester, som in-sekter, sopper, nematoder eller bakterier. En blanding med en raffinert petroleumsprøyteolje eller ekstra fin olje har vist seg å gi en større virkning enn en ren addisjonsvirkning ved bekjempelse av midd. Andre pesticider som forbindelsene med formelen I kan blandes med for å oppnå et bredere aktivitetsspektrum, omfatter: diazinon - 0,O-diethyl-0-(2-isopropyl-4-methyl-6- pyrimidyl)-f osf ortioat. It may be desirable or beneficial to mix the compounds with other agricultural pesticides or additives. Such mixtures often increase the effectiveness in combating mites and extend the range of control to other pests, such as insects, fungi, nematodes or bacteria. A mixture with a refined petroleum spray oil or extra fine oil has been shown to give a greater effect than a pure additive effect in combating mites. Other pesticides with which the compounds of formula I can be mixed to achieve a wider spectrum of activity include: diazinon - 0,O-diethyl-0-(2-isopropyl-4-methyl-6- pyrimidyl)-phospho orthioate.
disulfoton - 0,0-diethyl-S-2-(ethyltio)-ethylfosforditioat foråt - 0,0-diethyl-S-(ethylthio)-methylfosfordithioat oxamyl - S-methyl-1-(dimethylcarbamoyl)-N-[(methyl-carbamoyl)-oxy]-thioformimidat disulfoton - 0,0-diethyl-S-2-(ethylthio)-ethylphosphordithioate forate - 0,0-diethyl-S-(ethylthio)-methylphosphordithioate oxamyl - S-methyl-1-(dimethylcarbamoyl)-N-[(methyl- carbamoyl)-oxy]-thioformimidate

streptomycin - 2,4-diguanidin-3,5,6-trihydroxycyclohexyl-5-deoxy-2-o-(2-deoxy-2-methylamino-a-glycopyra-nosyl)-3-formylpentofuranosid streptomycin - 2,4-diguanidin-3,5,6-trihydroxycyclohexyl-5-deoxy-2-o-(2-deoxy-2-methylamino-α-glycopyranosyl)-3-formylpentofuranoside
Forbindelsene er spesielt egnet for beskyttelse av le-vende planter, som frukttrær, nøttetrær, prydtrær, skogstrær, grønnsaker, havevekster (omfattende prydvekster, små frukttrær og bærbusker) og korn- og frøplanter. Epletrær, ferskentrær, bomullsplanter, citrustrær, bønneplanter og jordnøttplanter er spesielt utsatt for angrep av midd eller bladlus og kan beskyttes ved anvendelse av forbindelsene med formelen I. For å sikre kontroll under hele vekstsesongen (f.eks. fra juni og ut august) kan flere tilførsler med ønskede mellomrom anvendes. The compounds are particularly suitable for the protection of living plants, such as fruit trees, nut trees, ornamental trees, forest trees, vegetables, garden plants (including ornamental plants, small fruit trees and berry bushes) and grain and seed plants. Apple trees, peach trees, cotton plants, citrus trees, bean plants and peanut plants are particularly susceptible to attack by mites or aphids and can be protected by the application of the compounds of formula I. To ensure control throughout the growing season (e.g. from June to the end of August) several additions at desired intervals are used.

Fremgangsmåtene for fremstilling av slike midler-er velkjente. Oppløsninger fremstilles ved ganske enkelt å blande bestanddelene. Findelte, faste blandinger fremstilles ved blanding og, som regel, nedmaling i en hammermølle eller en jetmølle. Suspensjoner fremstilles ved ' våtmaling (se US patentskrift nr. 3 060 084). Granulater og pellets kan fremstilles ved å sprøyte det aktive materiale på på forhånd dannede granulerte bærermate-rialer eller ved hjelp av agglomeringsteknikk. Se J.E. Browning, "Agglomeration", Chemical Engineering, A „ 'decernber 1967 , s. 147 ff., og Perry<1>s Chemical Engineer's Handbook, 4. utgave, McGraw-Hill,N.Y., 1963, s. 8 - 59 ff. The methods for producing such agents are well known. Solutions are prepared by simply mixing the ingredients. Finely divided, solid mixtures are produced by mixing and, as a rule, grinding down in a hammer mill or a jet mill. Suspensions are produced by wet painting (see US Patent No. 3,060,084). Granules and pellets can be produced by spraying the active material onto previously formed granulated carrier materials or by means of agglomeration techniques. See J.E. Browning, "Agglomeration", Chemical Engineering, A „ 'decernber 1967 , pp. 147 ff., and Perry<1>'s Chemical Engineer's Handbook, 4th ed., McGraw-Hill, N.Y., 1963, pp. 8 - 59 ff.

En annen flytende blanding som er spesielt egnet for anvendelse i liten målestokk-, er en "aerosol"-blanding som em-balleres under trykk i en egnet beholder. Den aktive bestanddel kan foreligge i en suspensjon, emulsjon eller oppløsning. På grunn av enkelhet ved fremstilling og bruk er oppløsningene foretrukket. Trykket kan tilføres ved hjelp av lavtkokende væs-ker, som propan eller klor-fluorcarboner, eller ved hjelp av forholdsvis oppløselige gasser, som carbondioxyd eller dinitrogenoxyd. Klorfluorcarboner er foretrukne på grunn av at de har en god oppløsningsevne og ikke er brennbare. Another liquid composition which is particularly suitable for small scale application is an "aerosol" composition packaged under pressure in a suitable container. The active ingredient can be present in a suspension, emulsion or solution. Due to simplicity of manufacture and use, the solutions are preferred. The pressure can be supplied by means of low-boiling liquids, such as propane or chlorofluorocarbons, or by means of relatively soluble gases, such as carbon dioxide or dinitrogen oxide. Chlorofluorocarbons are preferred because they have a good dissolving power and are not flammable.
