Description
Anvendelse av blandinger av neburon og Application of mixtures of neburon and
nitrofen til bekjempelse av ugress i kornåkere nitrofen for weed control in cornfields
etter spiring. after germination.
Fra fransk patentskrift 1.550.1^8 er det kjent herbicide preparater hvor det aktive materialinnhold er en blanding av en bisfenyl-eter med formelen og et ureaderivat med formelen From French patent document 1.550.1^8, herbicidal preparations are known in which the active material content is a mixture of a bisphenyl ether with the formula and a urea derivative with the formula
og det er kjent å bruke disse blandingene for å kontrollere ugressene blant kornavlinger, særlig blant mais. and it is known to use these mixtures to control weeds among cereal crops, particularly among corn.
Selv om det i det franske patentskrift ikke er påpekt at bruken Although it is not pointed out in the French patent document that the use
av blandingen er begrenset til et bestemt tidspunkt i utviklingen av kornavlingen, er det i alle eksemplene angitt at behandlingen utfores etter at froene er sådd, men for de begynner å spire. of the mixture is limited to a certain point in the development of the grain crop, in all the examples it is stated that the treatment is carried out after the seeds have been sown, but before they begin to germinate.
Dette fordi det ikke var ansett som mulig å benytte blandinger av denne type under andre betingelser siden det er vel kjent at en normal dose av nitrofen ikke kan brukes på allerede utviklede kornåkre, på grunn av at den virker fytotoksisk på kornplantene (Perrot og de Sarjas, hth Conference of the Columa, Vol. 1, side 65). This is because it was not considered possible to use mixtures of this type under other conditions since it is well known that a normal dose of nitrofen cannot be used on already developed grain fields, due to its phytotoxic effect on the grain plants (Perrot and de Sarjas , hth Conference of the Columa, Vol. 1, page 65).
Undersøkelser har nå vist at ved å redusere dosene av nitrofen, Studies have now shown that by reducing the doses of nitrofen,
noe som er mulig på grunn av den synergiske virkning som dette produkt viser når det blandes med neburon , har det vært mulig å bruke blandinger av disse forbindelsene som post-emergens (dvs. etter spiring) herbicider. which is possible because of the synergistic action that this product shows when mixed with neburon, it has been possible to use mixtures of these compounds as post-emergence (ie after germination) herbicides.
Denne oppdagelse er særlig interessant fordi det gjor det mulig This discovery is particularly interesting because it makes it possible
å forlenge perioden som disse blandingene kan benyttes i en vesentlig grad, slik at det er mulig å utfore sene behandlinger i tilfeller hvor det ikke var mulig å utfore, pre-emergens (dvs. forspiring) behandlinger, f.eks. på grunn av ugunstige atmosfæriske forhold. to extend the period in which these mixtures can be used to a significant extent, so that it is possible to carry out late treatments in cases where it was not possible to carry out, pre-emergence (ie pre-sprouting) treatments, e.g. due to adverse atmospheric conditions.
Undersokelsene hvor disse uventede egenskapene ble funnet ble ut-fort på åpen mark under normale driftsbetingelser ved å benytte områder med et areal lik 10 m p og med tre gjentagelser. I hvert tilfelle ble det bevart et kontrollområde for å måle en mulig stagnering av planten og gjore det mulig å observere den naturlige utvikling av ugress. The investigations where these unexpected properties were found were carried out on open ground under normal operating conditions by using areas with an area equal to 10 m p and with three repetitions. In each case, a control area was preserved to measure a possible stagnation of the plant and make it possible to observe the natural development of weeds.
I de forskjellige områdene var utviklingstrinnet av kornet i storrelse av 1 til 3 blader og den gjennomsnittlige utvikling av tilfeldige ugress-vekster tilsvarte to blader for differensieringen av skuddene. Dicotyledon-plantene var^ved det "lille" plantetrinn, som tilsvarer minst to virkelige blader. In the different areas, the development stage of the grain was in the size of 1 to 3 leaves and the average development of random weed growths corresponded to two leaves for the differentiation of the shoots. The dicotyledon plants were at the "small" plant stage, which corresponds to at least two true leaves.
Ugresset som var tilstede var folgende: The weeds that were present were as follows:
De oppnådde resultatene er fort opp i den folgende tabell, som for hver plante som ble undersokt indikerer prosent-odeleggelse oppnådd med neburon og nitrofen hver for seg og med forskjellige blandinger av disse med samme mengde av aktivt materiale pr. hektar. The results obtained are shown in the following table, which for each plant that was examined indicates the percentage destruction achieved with neburon and nitrofen separately and with different mixtures of these with the same amount of active material per hectares.
Disse resultatene viser tydelig fordelen ved å anvende blandinger av neburon 0g nitrofen som post-emergens herbicider, som ikke bare er meget effektive (medforer mellom 85% og 100% odeleggelse), men også meget selektive for korn. Det er bare ved bruk av blandinger på mer enn 2 kg nitrofen pr. hektar at det registreres en.lett fytotoksisk effekt på kornet. Det skal imidlertid bemerkes at denne fytotoksiske virkning bare er midlertidig og medforer ingen merkbar reduksjon i oppnådd utbytte med hensyn til vekt av samlet korn. These results clearly show the advantage of using mixtures of neburon 0g nitrofen as post-emergence herbicides, which are not only very effective (resulting in between 85% and 100% destruction), but also very selective for grain. It is only when using mixtures of more than 2 kg of nitrofen per hectare that a slight phytotoxic effect on the grain is recorded. It should be noted, however, that this phytotoxic effect is only temporary and does not entail any appreciable reduction in the obtained yield with respect to the weight of collected grain.
Disse resultatene bekrefter også det synergiske fenomen som oppnås ved pre-emergens undersøkelser, da det ved omregning av prosent odeleggelse oppnådd ved en serie prover til gjennomsnittstall ble folgende funnet: These results also confirm the synergistic phenomenon that is achieved in pre-emergence investigations, as the following was found when converting the percentage of decomposition obtained in a series of samples to average figures:
61% for Aitrofen benyttet alene i doser på h kg/ha, 61% for Aitrofen used alone in doses of h kg/ha,
50% for neburon r benyttet alene i doser på k kg/ha 50% for neburon r used alone in doses of k kg/ha
og henholdsvis 9h%, 93$ og 91$ for de forskjellige blandinger av neburon og nitrofen som benyttes med samme totale dose på h kg/ha. and respectively 9h%, 93$ and 91$ for the different mixtures of neburon and nitrofen used with the same total dose of h kg/ha.
Dette bekrefter de okonomiske fordelene ved bruk av blandinger av pre-emergenstypen som gjor det mulig å oppnå en bedre odeleggelse av ugress ved bruk av samme totale mengde av aktivt materiale pr. enhet av overflate-areal og således senkes utgiftene ved behandlingen. This confirms the economic advantages of using mixtures of the pre-emergence type, which make it possible to achieve a better destruction of weeds using the same total amount of active material per unit of surface area and thus the costs of the treatment are lowered.
For praktisk utnyttelse av blandingene av neburon og nitrofen anvendes disse i vanlige preparatformer, fremstilt i overens-stemmelse med vanlig teknikk, slik som f.eks. beskrevet i det nevnte franske patentskrift. For practical utilization of the mixtures of neburon and nitrofen, these are used in usual preparation forms, prepared in accordance with usual techniques, such as e.g. described in the aforementioned French patent document.
