Description
(54) Spůsob biologického stanovovania přítomnosti reziduí herbicídov určených proti pýru(54) Method for the biological determination of the presence of residues of herbicides against wheat
Spůsob biologického stanovenia přítomnosti rezidui herbicídov určených proti pýru, na báze kyseliny trichlóroctovej alebo jej solí, kyseliny 2,2-dichlórpropiónovej a trlchlóracetaldehydu v pode.Method for the biological determination of the presence of residues of herbicides against wheat, based on trichloroacetic acid or its salts, 2,2-dichloropropionic acid and trichloroacetaldehyde in a pod.
Spůsob spočívá vo vizuálnom posúdení inhibície tvorby antokyanu na klíčkoch obiliek žita, ktoré vyklíčili po vysadení na navlhčených vzorkách testovaných půd a osvětlení o intenzitě najmenej 500 luxov. Kllčenie může prebiehať pri běžných teplotách, s výhodou pri teplotách 23 až 25 °C.The method consists of a visual assessment of the inhibition of anthocyanin formation on the germ of rye caryopses which have been germinated after planting on moistened samples of test soil and illumination with an intensity of at least 500 lux. The germination can take place at normal temperatures, preferably at 23-25 ° C.
Predmetom vynálezu je spósob biologického stanovovania přítomnosti rezidui herbicídov určených proti pýru na báze kyseliny trichlóroctovej alebo jej solí, ďalej kyseliny 2,2-dichlórpropiónovej a trichlóracetaldehydu v půdě, vizuálnym posúdením inhibície tvorby antokyanu.The present invention provides a method for the biological determination of the presence of trichloroacetic acid herbicide residues or salts thereof, 2,2-dichloropropionic acid and trichloroacetaldehyde in the soil by visual assessment of inhibition of anthocyanin formation.
. Herbicidy na báze kyseliny trichlóroctovej alebo jej solí, ďalej kyseliny 2,2-dlchlórpropiónovej a trichlóracetaldehydu isav nasej pofnohospodárskej praxi najčastejšie používajú na nlčenle pýru. Voči týmto herblcídom á ich rezíduám v pode sú však velmi citlivé trávy včítane obilnin. Preto by sa herbicidy uvedeného typu malí v praxi, ako ochrana iproti pýru, používat predovšetkým před statím plodin, ktoré ich iwíďuá znášajiú, ako je cukrová řepa, zemiaky a podobné. Použitie herbicídov před siatím jarných obilnin je pódia doteraz zaužívaných metodik možné iba vtedy, ak je předpoklad, že po ich aplikácii spadne do zamrznutia pódy váčšie množstvo zrážok (80 až 120 mm). V případe, že sa uvedené herbicidy používajú před siatím ozimín, je leh aplikácia spojená s rizikom poškodenia obilniny, pokial' nie sú rezidua před siatím obilniny priamo zistené. Poškodenle obilniny sa prejavuje predovšetkým v blokování rastu klíčkov a listov. Rast koreňov je ovplyvnený menej.. Herbicides based on trichloroacetic acid or salts thereof, 2,2-dichloropropionic acid and trichloroacetaldehyde, and in our agricultural practice, are most often used for the production of wheat. However, grasses, including cereals, are very sensitive to these herbicides and their underwater residues. Therefore, in practice, herbicides of this type should be used, in particular, as protection against crop, in particular in crop plants which are tolerated by them, such as sugar beet, potatoes and the like. The use of herbicides prior to the sowing of spring cereals is only possible if the methodologies used to date have been used if there is a presumption that a significant amount of precipitation (80 to 120 mm) will fall into the freezing ground after their application. In the case where said herbicides are used prior to sowing, the application is associated with a risk of damage to the cereal, unless residues are directly detected before sowing the cereal. Damaged cereals are manifested primarily in blocking the growth of germ and leaves. Root growth is less affected.
Z literatúry je známy poznatok, že heřblcídne prostriedky na báze kyseliny 2,2-dlchlórpropiónovej spósobujú odfarbovanle červenej kapusty inhibíclou tvorbý antokyanu (Chemische Unkrautbekampfung, s. 206, 1975).It is known in the literature that 2,2-dichloropropionic acid-based herbicidal compositions cause the color of red cabbage to inhibit anthocyanin production (Chemische Unkrautbekampfung, p. 206, 1975).
Teraz sa zistilo, že přítomnost rezidui herbicídov určených proti pýru, na báze kyseliny trichlóroctovej alebo jej solí a dalej kyseliny 2,2dichlórpropiónovej a trichlóracetaldehydu v póde, možno stanovit biologickým spósobom, vizuálnym posúdením inhibície tvorby antokyanu.It has now been found that the presence in the soil of residues of herbicides against wheat, based on trichloroacetic acid or its salts and other 2,2-dichloropropionic acid and trichloroacetaldehyde can be determined by a biological method, by visual assessment of inhibition of anthocyanin formation.
Podstata vynálezu spočívá v tom, že sa vizuálnemu posúdeniu podrobia najmenej 1 cm dlbé klíčky obiliek žita, vyklíčené po vysadení a Individuálně odobraté navlhčené vzorky testovaných pód a vystavené osvetleniu o intenzitě najmenej 500 luxov. Je výhodné, ak obilky žita klíčia pri teplote 23 až 25 °C.The principle of the invention is that at least 1 cm long germ of rye caryopses, germinated after planting and individually collected moistened samples of the test pod and subjected to illumination of at least 500 lux, are subjected to visual examination. It is preferred that the rye kernels germinate at a temperature of 23-25 ° C.
Na vzorkách pód obsahujúcich škodlivé rezíduá herbicídov sú klíčky obiliek žita blele. Na vzorkách pód bez škodlivých rezidui je možné pozorovat fialové zafarbenie klíčkov žita. Testované vzorky pód sa porovnávajú s kontrolnou vzorkou neobsahujúcou škodlivé rezíduá.On pod samples containing harmful herbicide residues, the sprouts of rye caryopses are white. Violet staining of rye germs can be observed on samples without harmful residues. Pod test samples are compared to a control sample free of harmful residues.
Na vzorkách pód, kde nedošlo k fialovému zafarbeniu obiliek žita je potřebné oddialiť siatie obilním, připadne až na j.arné obdobie.On samples of podiums where there was no violet discoloration of rye kernels, it is necessary to delay cereal sowing, eventually until the spring season.
Pře test je možné použit aj obilky pšenice a jačmeňa, ale pri klíčení Jačmeňa sa antokyan netvoří a při klíčení pšenice je jeho tvorba menej výrazná. Vplyv rezidui na týchto druhoch obilovin je možné posúdiť až po dlhšom čase, pričom sa posudzuje inhibícia klíčenia, dižka klíčkov a dižka listov.Wheat and barley caryopses can also be used in the test, but no anthocyanin is formed in the germination of barley and its formation is less pronounced in wheat germination. The impact of residues on these cereal types can only be assessed for a longer period of time, assessing germination inhibition, germ length and leaf length.
Sposob biologického stanověnia přítomnosti rezidui herbicídov proti pýru vo vzorkách pód podlá vynálezu je jednoduchý, rýchly, spolahlivý a nenáročný na přístrojová techniku. Je možné využit ho v podmienkach okresných pólnohospodárskych laboratórií,'. laboratórií UKSUPu a UKZtJZu a podobné.The method of biological determination of the presence of herbicide residues against rye in the samples according to the invention is simple, fast, reliable and easy to use. It can be used in the conditions of the district agricultural laboratories. UKSUP and UKZtJZ laboratories and the like.
