(54) Prostriedok na zvýšenie úrody kukuřice
Prostriedok na zvýšenie úrody kukuřice a zlepšeme jej technologickej kvality obsahujúci ako účinnú zložku 3-metyl-4-amino-6-fenyl-l,2,4-triazín5(4H)-on vzorca
Predmetom vynálezu je prostriedok na zvýšenie úrody a kvality kukuřice obsahujúci ako účinnú! zložku 3-metyl-amino-6-fenyl-l,2,4-triazín- í 5(4H)-on. I
Kukurica' patří medzi najvýznamnejšie agrono- í mické plodiny. Je vysoko intenzívnou krmovinou. Je preto významným intenzifikačným faktorom ! celej živočíšnej· výroby, a to ako objemové krmivo tak i zrno. Úsilie o zvýšenie úrody kukuřice a jej > kvality je celosvětové. Významné miesto pri inten- ’ zifikácii jej výroby hrajú chemizačné prvky, ; a z nich rastúci význam zaujímajú bioregulátory, to značí zlúčeniny, pomocou ktorých je možné dosiahnuť lepšieho využitia úrodového genofondu plodiny.
Jedným z používaných bioregulátorov do kukuřice je 2,4-dinitro-6-sek. butylfenol, ktorý našiel široké použitie v niektorýeh štátoch s rozvinutou polnohospodárskou výrobou. Publikované výsledky, ktorých sa s bioregulátorom dosahuje, pouka- 1 zujú na variabilitu v jeho účinku, i ked zváčša sú i jeho účinky na výnosy pozitivně.
Teraz sa zistilo, že zvýšenie úrody kukuřice a jej technologickej a nutričnej kvality možno dosiahnuť aplikáciou prostriedku obsahujúceho ako účinnú zložku 3-metyl-4-amino-6-fenyl-l,2,4-triazín5(4H)-on vzorca
použitý v množstve 2,5 až 60 g na hektar.
Regulácia úrody kukuřice prostriedkom podía vynálezu sa dosahuje aplikáciou v róznych štádiách vývinu plodin a to buď před zasiatím alebo preemergentne alebo postemergentne v časovom období 3 týždne až 7 mesiacov před zberom. Prostriedok na zvyšovanie úrody móže prijať plodina buď prostredníctvom pódy, t. j. cez kořene alebo postrekom prostredníctvom listu. Výsledkom pósobenia zlúčeniny na rastliny kukuřice sú změny v ich fyziologických procesoch, ktoré sa prejavujú v regulácii asimilačnej produkcie a dochádza k zvýšenému ukladaniu asimilátov do hospodářsky významných orgánov. Tým sa dosiahne nielen zvýšenie úrody, ale i zlepšenie technologickej kvality nutričnej hodnoty plodiny, ale i zníženého infekčného tlaku hubových ochorení, čo vedie k značné- ! mu ekonomickému přínosu pri pěstovaní plodiny. Je známe, že účinná látka prostriedku podlá vynálezu má silné herbicídne účinky a našla použitie ako selektívny herbicid do cukrovej a krmnej řepy (H. Lembrich: Pflanzenschutz — Nachrichten | Bayer 31 (1978) 197-228; W. Kolbe: Pflanzenschutz — Nachrichten Bayer 31 (1978) 229—241, patenty NDR 118· 365, 119 117). !
Účinnú látku ‘ prostriedku podfa vynálezu je j možno připravit známými postupmi z literatúry, uvedenými v čs. pat. 174 882, 179 931.
Aplikáciou prostriedku podlá vynálezu je možno uskutočniť postrekom, formou zálievky, rozprášením, zahmlovaním a to na celé rastliny alebo na povrch pódy alebo zapravením do pódy do požadovanej híbky, bud plošným alebo pásovým ošetřením medzi riadky alebo do riadkov.
Vhodnou aplikačnou formou sú roztoky, emulzie, disperzie, suspenzie vodné alebo olejové, zmáčatelné prášky, popraše, posypy, pasty, granuláty alebo mikrogranuláty, za přítomnosti tekutých | a/alebo pevných nosičov, připadne riedidiel, zmáί čadiel, adhezív, pojidiel, modifikátorov, povrcho! vo aktívnych látok, emulgačných činidiel a/alebo dispergačných ? činidiel, látok proti peneniu, farbív.
Zmáčatelné prášky je možné připravit' tak, že sa účinná látka zmieša s dispergátormi a práškovými nosnými látkami na homogénnu zmes a tá sa rozomelie. Ako nosné látky prichádzajú do úvahy například mastenec, infusoriová hlinka, kaolín, bentonit, uhličitan vápenatý, siloxid, piesok, dřevitá múčka a/alebo iný materiál rastlinného póvodu. !

SUMMARY OF THE INVENTION The present invention relates to a composition for improving the yield and quality of maize containing as active ingredient. 3-methyl-amino-6-phenyl-1,2,4-triazin-5 (4H) -one; I
Corn 'is one of the most important agronomic crops. It is a highly intensive fodder. It is therefore an important intensification factor! of all animal production, both by volume and grain. Efforts to increase the corn crop and its quality> are worldwide. Chemical elements play an important role in the intensification of its production; and bioregulators are of increasing importance, that is to say compounds which can be used to make better use of the crop's gene pool.
One of the maize bioregulators used is 2,4-dinitro-6-sec. butylphenol, which has found widespread use in some countries with developed agricultural production. The published results achieved with the bioregulator point to variability in its effect, although its effects on yields are generally positive.
It has now been found that an increase in maize crop and its technological and nutritional quality can be achieved by the application of a composition comprising as active ingredient 3-methyl-4-amino-6-phenyl-1,2,4-triazin5 (4H) -one of the formula
used in an amount of 2.5 to 60 g per hectare.
Control of the maize crop by the composition of the invention is achieved by application at various stages of crop development, either before sowing or preemergence or postemergence for a period of 3 weeks to 7 months prior to harvest. The crop enhancer can take up the crop either through the soil, ie through the roots or by spraying through the leaf. The effect of compounding on maize plants results in changes in their physiological processes, which are reflected in the regulation of assimilation production and increased assimilation of the assimilates into economically important organs. This achieves not only an increase in the crop, but also an improvement in the technological quality of the nutritional value of the crop, but also a reduced infectious pressure of fungal diseases, which leads to a considerable increase in the production rate. economic benefit in growing the crop. It is known that the active ingredient of the composition according to the invention has potent herbicidal effects and has found use as a selective herbicide in sugar and fodder beet (H. Lembrich: Pflanzenschutz-Nachrichten | Bayer 31 (1978) 197-228; W. Kolbe: Pflanzenschutz-Nachrichten Bayer 31 (1978) 229-241, GDR patents 118,365,119,117). !

Even in graduated doses of the application solution. Eight weeks after treatment, plant height, green matter and dry matter yields were measured for one part of the plants and compared to control. Other plants harvested only at the stage of ripening were monitored for grain yield and coped with untreated controls.
Example 5
In the vegetation test, the effectiveness of the crop-enhancing agent and the quality of the maize for green fodder were compared. The composition of Example 2 was applied to the pod in Mitscherlich flasks in three graduated doses in amounts of 2.25; 4.45 and 9 mg of active ingredient per container (corresponding to 15.30 and 60 g / ha respectively). The nutrient dose corresponded to 107.5 kg N, 53 kg P and 33 kg Kna per ha. Soil moisture was maintained at 60-80% of the full water capacity by the grout. Pre-germinated maize seeds TO-510 were seeded (7 vol.) In 20 pieces per pot in 6 replicates. During the vegetation growth, the above-ground parts of the plants were harvested 4 times in the 5th leaf stage (19th VI) as well as in the 7th leaf stage (25th VII) and in the subsequent stages of the 26th VIII. and 15. X. The dry matter of the above-ground part of the untreated variant at the last harvest (15 X.) was chosen to be 100% and compared with the values of the other untreated variants and the variants treated with graduated doses of the active substance. This was the increment; corn biomass during the vegetation season of plants growing in the presence of a regulator with control; release to the podium compared to control.
Crop quality and ripening were monitored by the content of dry matter in green matter during vegetation. The dry matter content of the above-ground part of the plants was determined in four growth stages.
