Forbindelserne med formel I er særligt egnede som kemiske gameto-cider ved cereal ieafgrøder, såsom hvede, byg, majs, ris, durra, hirse, havresorter, rug og lignende. Anvendt som kemiske gametocider inducerer forbindelserne effektivt en høj grad af sterilitet i de behandlede 30 planter uden at forårsage væksti nhi bering af betydning hos de behandlede planter. Forbindelserne med formel I frembringer også andre plantevækstregulerende reaktioner, såsom f.eks. i nhi bering af frødannelse hos uønskede monocotarter til regulering af ukrudtsgræs, regulering af blomstring, regulering af frugtsætning og inhibering af frødannelse i ikke-35 cereal iearter, regulering af modning og andre beslægtede vækstregulerende reaktioner.
Forbindelserne med formel I tilføres, når de anvendes som plantevækstregulerende midler, i enhver mængde, som vil være tilstrækkelig til
DK 158350B
12 at bevirke den ønskede plantereaktion uden at forårsage nogen uønsket eller phytotoxisk reaktion. F.eks. tilføres forbindelserne, når de anvendes som kemiske gametocider, almindeligvis planterne, som skal behandles i en mængde på ca. 0,035 til ca. 22,4 kg/ha, og fortrinsvis ca.
5 0,14 til ca. 11,2 kg/ha. Mængden, der tilføres vil variere i afhængighed af plantearterne, som behandles, forbindelsen, der anvendes til behandlingen og lignende faktorer.
En foretrukket metode til tilførsel af en forbindelse med formel I som plantevækstregulerende middel er ved bladtilførsel. Når denne metode 10 benyttes, frembringes gametocid aktivitet mest effektivt, når forbindelser tilføres forud for meiose og fortrinsvis efter blomsterinitiering. Forbindelserne med formel I kan også tilføres i form af en frøbehandling ved udblødning af frøene i et flydende præparat indeholdende den aktive forbindelse eller ved overtrækning af frøene med forbindelsen. Ved frø-15 behandlingstilførsel vil forbindelserne sædvanligvis blive tilført i en mængde på ca. 1/4 til ca. 10 kg pr. 112 kg frø. Forbindelserne kan også tilføres jorden eller ved risafgrøder vandoverfladen.
Forbindelserne med formel I kan anvendes som plantevækstregulatorer enten enkeltvis eller i blanding. De kan f.eks. anvendes i kombination 20 med andre piantevækstregulatorer, såsom auxiner, gibberelliner, morphac-tiner, ethylen-afgivende midler, såsom ethephon, pyridoner, cytokininer, maleinsyrehydrazid, ravsyre-2,2-dimethylhydrazid, cholin og dets salte, (2-chlorethyl)-trimethylammoniumchlorid, triiodobenzoesyre, tributyl- 2,4-dichlorbenzylphosphoni umchlori d, polymere N-vi nyl-2-oxazoli di noner, 25 tri(dimethylaminoethyl)-phosphat og dets salte og N-dimethylamino-1, 2,3,6-tetrahydrophthalamidsyre og dens salte, 2,3-dichlori sosmørsyre og dens salte og 3-(4-chlorphenyl)-6-methoxy-s-triazin-2,4-(lH,3H)-dion.
Under visse betingelser kan forbindelserne med formel I med fordel anvendes sammen med andre jordbrugskemikalier, såsom herbicider, fungi-30 cider, insekticider og plantebaktericider.
En forbindelse med formel I kan tilføres vækstmediet eller planter-ne, som skal behandles, enten i sig selv eller som det almindeligvis sker, som komponent i et vækstregulerende præparat eller sammensætning, som også omfatter en agronomisk acceptabel bærer. Med "agronomisk accep-35 tabel bærer" menes enhver substans, som kan anvendes til opløsning, dis-pergering eller spredning af en forbindelse i præparatet uden at svække effektiviteten af forbindelsen, og som i sig selv ikke har nogen skadelig virkning af betydning på jorden, apparaturet, afgrøderne eller det
DK 158350B
13 agronomiske milieu. Også blandinger af forbindelser med formel I kan anvendes i en hvilken som helst af disse sammensætninger. Præparaterne kan være af enten fast eller flydende sammensætning, eller de kan være opløsninger. F.eks. kan forbindelserne formuleres som befugtelige pulvere, 5 emulgerbare koncentrater, puddere, granulater, aerosoler eller letflydende emulsionskoncentrater. I sådanne sammensætninger strækkes forbindelserne med en flydende eller fast bærer, og om ønsket inkorporeres passende overfladeaktive midler.
Detaljer vedrørende egnede sammensætninger og andre oplysninger, 10 som er relevante for den foreliggende opfindelse, kan findes i dansk patentansøgning nr. 1060/78, som svarer til U.S.A. patentansøgning nr.
776.394, der er indleveret den 10. marts 1977.
Forbindelserne med formel I kan tilføres som sprøjtemidler ved almindeligt anvendte metoder, såsom i form af konventionelle hydrauliske 15 sprøjtemidler, forstøvede sprøjtemidler og puddere. Ved lav-volumen tilførsler anvendes sædvanligvis en opløsning af forbindelsen. Fortyndingen og tilførselsvolumenet vil sædvanligvis afhænge af sådanne faktorer som typen af udstyr, der anvendes, tilførselsmåden, arealet, som skal behandles, og typen og udviklingsstadiet af afgrøden, som skal behandles.
20 De i tabel II nedenfor anførte data viser gametocid aktivitet af typiske forbindelser med formel I. Disse data opnåedes ved hjælp af følgende fremgangsmåde.
En stakvarietet (Fielder) og en stakfri varietet (Mayo-64) af vårhvede plantedes i en mængde på 6-8 frø pr. 15,24 cm potte indeholdende 25 et sterilt medium af 3 vægtdele jord og 1 vægtdel humus. Planterne dyrkes under kortdagsbetingelser (9 timer) i de første 4 uger for at opnå god vegetativ vækst før blomsterinitiering. Planterne flyttes derefter til langdagsbetingelser (16 timer), som frembringes ved hjælp af højintensitetslyskilder i væksthuset. Planterne gødes 2, 4 og 8 uger 30 efter plantning med en vandopløselig gødning (N 16%, P 25%, K 16%) i en mængde på 1 teskefuld (ca. 5 ml) pr. 3,8 liter vand og sprøjtes hyppigt med det under varemærket "Isotox" solgte insekticid til bladlusbekæmpelse og pudres med svovl til meldugbekæmpelse.
Forbindelserne, som skal undersøges, tilføres bladvæksten på de med 35 stakke forsynede hunkønsplanter, når disse planter når flagbi ads- emergensstadiet (stadium 8 på Feekes' skala). Alle forbindelser tilføres i et bærervolumen på 468 1/ha indeholdende et overfladeaktivt middel, såsom "Triton X-100" i en mængde på 30 g/100 1.

Efter aksemergens men før anthesis indesluttes 4-6 aks pr. potte i en pose for at forhindre udkrydsning. Ved de første tegn på blomsteråbning, krydsbestøves to aks pr. potte med den stakfri hankønsstamvækst under anvendelse af tilnærmelsesmetoden. Så snart frøene bliver tydeligt 5 synlige, måles akslængden, og frøene pr. småaks tælles i såvel indesluttede som krydsede aks. Hankønssterilitet kan så beregnes som procentvis inhibering af frøsætning i indesluttede aks på behandlede planter. Efter fuld udvikling kan frøene fra krydsede aks udplantes til bestemmelse af hybridi seri ngsprocent.
10 Procent sterilitet beregnes ud fra følgende formel:
Sc - St % sterilitet =-x 100
Sc 15
Sc = frø/småaks i indesluttede aks på kontrolplanter.
St = frø/småaks i indesluttede aks på behandlede planter.
I tabel II opsummerer typiske resultater opnået ved undersøgelse af 20 forbindelser med formel I. En betyder, at der ikke blev foretaget nogen undersøgelse ved den angivne mængde.
