Description
Middel til bekjempelse av ugress. Weed control agent.
Det er kjent å bruke forskjellige kje-miske stoffer til bekjempelse av ugress før kulturplantenes oppvekst. Det er også tid-ligere foreslått å forbinde denne bekjempelse av ugress med en gjødsling og å blan-de de aktive stoffer med større mengder gjødningsstoffer i fast tilstand, så at gjød-ningsstoffene samtidig tjener som forde-lingsmiddel for midlene til bekjempelse av ugress. It is known to use various chemical substances to control weeds before the cultivation plants grow. It has also previously been proposed to combine this weed control with fertilization and to mix the active substances with larger quantities of fertilizers in solid state, so that the fertilizers simultaneously serve as a distribution agent for the weed control agents.
I henhold til oppfinnelsen skaffes der nå nye ugressbekjempelsesmidler som inneholder halogenerte, eventuelt alkylsub-stituerte fenoxykarbonsyrer og vannopp-løselige fosforsyresalter. Det karakteris-tiske trekk ved disse nye ugress-bekjem-pelsesmidler er at de består av vandige sprøytevæsker til ugressbekjempelse etter planters spiring, hvilke sprøytevæsker ved siden av fenoxykarbonsyrene og/eller salter av sådanne syrer inneholder et i vann oppløselig natrium-, kalium- eller ammo-niumsalt av en anorganisk fosforsyre, i mengder fra 0,5 til 50 g pr. liter, fortrinsvis fra 0,5 til 15 g pr. liter, idet der pr. In accordance with the invention, new weed control agents are now obtained which contain halogenated, optionally alkyl-substituted phenoxycarboxylic acids and water-soluble phosphoric acid salts. The characteristic feature of these new weed control agents is that they consist of aqueous spray liquids for weed control after plant germination, which spray liquids, in addition to the phenoxycarboxylic acids and/or salts of such acids, contain a water-soluble sodium, potassium or ammonium salt of an inorganic phosphoric acid, in amounts from 0.5 to 50 g per litre, preferably from 0.5 to 15 g per litres, as per
1 del fenoxykarbonsyre er tilstede opp til 1 part phenoxycarbonic acid is present up to
6 deler fosforsyresalt, samt at sprøytevæs-kene har en pH-verdi på 6 eller høyere. 6 parts phosphoric acid salt, and that the spray liquids have a pH value of 6 or higher.
De halogenerte, eventuelt alkylsubsti-tuerte fenoxykarbonsyrer kan f. eks. være methylklor-fenoxy-, diklorfenoxy- og triklorfenoxyeddiksyre, -propionsyre og The halogenated, possibly alkyl-substituted phenoxycarboxylic acids can e.g. be methylchlorophenoxy-, dichlorophenoxy- and trichlorophenoxyacetic acid, -propionic acid and
-smørsyre og deres salter, som f. eks. natriumsaltet av triklorfenoxyeddiksyren og av methylklorfenoxyeddiksyren, diethyl-aminsaltet av methylklorfenoxypropion- -butyric acid and their salts, such as the sodium salt of trichlorophenoxyacetic acid and of methylchlorophenoxyacetic acid, the diethylamine salt of methylchlorophenoxypropion-
syre, og andre forbindelser om hvilke det er kjent at de i stor utstrekning brukes til bekjempelse av ugress. acid, and other compounds which are known to be widely used for weed control.
Når sprøytemidler som inneholder sli-ke forbindelser tilsettes en liten mengde av de nevnte vannoppløselige salt av en fosforsyre, f. eks. alkalimetallsalter av or-tofosforsyre, pyrofosforsyre og polyfosfor-syrer, oppnåes en overraskende sterkere ødeleggelse av ugress enn med sprøyte-midler uten sådanne tilsetningsmidler. When pesticides containing such compounds are added a small amount of the aforementioned water-soluble salt of a phosphoric acid, e.g. alkali metal salts of orthophosphoric acid, pyrophosphoric acid and polyphosphoric acids, a surprisingly stronger destruction of weeds is achieved than with pesticides without such additives.
Ifølge oppfinnelsen tilsettes sprøyte-midlene fosfater i så små mengder at de ikke utøver noen virkning som gjødnings-stoff. I alminelighet er mengder på mindre enn tilsvarende 10 kg KHJPO, pr. hektar tilstrekkelige, imidlertid oppnåes der allerede med meget mindre mengder enn denne betydelig økning av den herbicide virkning, som det fremgår av de forsøks-resultater som angis i det følgende. According to the invention, phosphates are added to the spraying agents in such small quantities that they have no effect as fertiliser. In general, quantities of less than the equivalent of 10 kg of KHJPO, per hectare sufficient, however, a significant increase in the herbicidal effect is already achieved with much smaller quantities than this, as is evident from the experimental results set out below.
Det er videre funnet å være fordelak-tig at sprøytevæsken har en pH-verdi på 6 eller høyere. Dette medfører blant annet den fordel at de aktive stoffer blir lettere oppløselige, idet væskene i mere surt me-dium lett blir uklare på grunn av utfelt ak-tivt stoff. It has also been found to be advantageous that the spray liquid has a pH value of 6 or higher. This entails, among other things, the advantage that the active substances become more easily soluble, as liquids in a more acidic medium easily become cloudy due to precipitated active substance.
Som eksempel 4 i det følgende viser, ble det fastslått at ved tilstrekkelig gjøds-let og selv ved sterkt overgjødslet jord, inntrer der en betydelig økning av virkningen ved tilsetning av fosfater til sprøy-tevæsker. At det her dreier seg om en ek-te synergistisk forhøyelse av effekten fremgår av det faktum at det ikke ble iakttatt noen beskadigelse av ugressplan-ter ved sprøytning med fosfater alene (se eksempel 7). As example 4 in the following shows, it was established that with sufficiently fertilized and even with heavily overfertilized soil, there is a significant increase in the effect of adding phosphates to spray liquids. That this is a true synergistic increase in the effect is evident from the fact that no damage to weed plants was observed when spraying with phosphates alone (see example 7).
Anvendelsen av ugressbekjempelses-midlene ifølge oppfinnelsen fører altså til en fullstendig ny virkning som det ikke er mulig å utlede av det som hittil er kjent på området. The use of the weed control agents according to the invention thus leads to a completely new effect which it is not possible to derive from what is known in the field so far.
Denne overraskende gunstige virkning fremgår av de eksempler på utførelsesfor-mer for oppfinnelsen som er angitt i det følgende. This surprisingly favorable effect is evident from the examples of embodiments of the invention which are given below.
Den forsterkede virkning ble påvist ved forsøk i drivhus ved forskjellige temperaturer og under anvendelse av dikotyle planter av 5 forskjellige familier som opp-ført nedenfor. Herved er almengyldighe-ten av forsterkningen av virkningen påvist : 3aryophyllaceae: Stellaria media Dompositae: Agera turn mexicanum Centaurea cyanus Galinsoga parviflora Druciferae: Sinapsis alba 3chophulariaceae: Antirrhinum majus Solanaceae: Solanum lycopersicum The enhanced effect was demonstrated by experiments in greenhouses at different temperatures and using dicotyledonous plants of 5 different families as listed below. Hereby, the general validity of the strengthening of the effect has been demonstrated: 3aryophyllaceae: Stellaria media Dompositae: Agera turn mexicanum Centaurea cyanus Galinsoga parviflora Druciferae: Sinapsis alba 3chophulariaceae: Antirrhinum majus Solanaceae: Solanum lycopersicum
I eksempel 3 i det følgende vises det at ienne forsterkning av virkningen også inntreffer på friland, uten at ugressbe-kjempelsesmidlenes selektivitet påvirkes. In example 3 in the following, it is shown that an enhancement of the effect also occurs in open fields, without the selectivity of the herbicides being affected.
De verdier for toksisiteten som er angitt i de følgende eksempler er middelver-dier av et større antall bedømmelser under forsøkene. Bedømmelsene ble foretatt efter en skale hvor 0 betegner ubeskadi-gede planter og 10 betegner drepte planter. The values for the toxicity given in the following examples are mean values of a larger number of assessments during the experiments. The assessments were made according to a scale where 0 denotes undamaged plants and 10 denotes killed plants.

Utsæd ble foretatt 23. april 1957 og sprøytning 14. juni 1957 med 600 liter pr. hektar. Parsellene var ved sprøytingen nesten utelukkende bevokset i middels grad med Galinsoga parviflora i kimblad-stadiet inntil 8-bladstadiet. Behandlingen ble utført med kaliumsaltet av metylklor-fenoxyeddiksyre (MCPA-K). Sowing was carried out on 23 April 1957 and spraying on 14 June 1957 with 600 liters per hectares. At the time of spraying, the plots were almost exclusively vegetated to a medium extent with Galinsoga parviflora in the cotyledon stage up to the 8-leaf stage. The treatment was carried out with the potassium salt of methylchlorophenoxyacetic acid (MCPA-K).
