Description
149032 i
En sent modnet bladrig bestand, sekundære skud og ukrudt er de faktorer, som mest vanskeliggør mejetærskning af ært, hestebønne, vårrybs og vårraps. Følgen er ofte store kvantitative og især kvalitative afgrødetab. Der findes kemiske 5 midler til at dræbe løv, som samtidig også kan bekæmpe ukrudt. Sådanne midler er blandt andet organiske nitrogenholdige forbindelser, såsom paraquat og diquat samt også organiske phos-phorsyrederivater. Af disse forbindelser bliver dog giftige rester tilbage i afgrøden, hvorfor man ikke har kunnet god- 10 kende dem til anvendelse. Blandt uorganiske forbindelser kan man anvende blandt andet mineralsyrer, såsom svovlsyre (Fryer, J.,Makepeace, R., Weed control handbook II Recommendation 6, udgave Bartholomew Press, England 1970, side 37). Svovlsyren, som er en stærk syre, ætser sprøjten og er skadelig for mar- 15 kerne. Fra beskrivelsen til dansk patent nr. 50156 kendes et ukrudtdræbende middel, som indeholder mellem 4,8 og ikke væsentligt over 22 vægtprocent fri phosphorsyre. Dette middel tjener også til ødelæggelse af bakterier og snyltesvampe og anvendes på et tidligt stadium af en kornafgrødes vækst.
20 Den foreliggende opfindelse angår en fremgangsmåde til at dræbe løvet hos ært, hestebønne, vårrybs og vårraps samt ukrudt ved sprøjtning med et inineralsyremiddel før mejetaerskning, hvilken fremgangsmåde er ejendommelig ved, at plantebestanden, som skal mejetærskes, 1-2 uger før mejetærskningen sprøjtes med ca.
25 400 1 pr. hektar af en 15-20%'ig orthophosphorsyreopløsning, som indeholder ca. 0,25% overfladespændingsnedsættende middel, og at der yderligere foretages en sprøjtning af dyrkningsarealerne med samme opløsning, inden den pågældende dyrkede plante er kommet op.
30 Den første sprøjtning dræber alt det ukrudt, som på sprøjtningstidspunktet er kommer op. Sprøjtningen 1 til 2 uger før mejetærskningen bevirker en større og kvalitativt bedre høst end ved sædvanlig mejetærskning. Under meget vanskelige høstforhold kan en allerede kasseret afgrøde på denne måde reddes.
