Pickling (crop protection)

from Wikipedia, the free encyclopedia
Stain on maize kernels, they are naturally yellow, the stain is noticeable through dye
Rapeseed, which is naturally black, is colored by the growers in their respective colors; leftovers from different growers were mixed here

With pickling or pickling or seed dressing is referred to in the agriculture, forestry and in landscaping and horticulture treatment of seeds and plants with pesticides to the sowing or planting antifungal ( emergence diseases ) and from pests (mostly insects or birds ) to protect, to which seedlings and young plants are particularly susceptible. Grain seeds are treated with fungicides against emergence diseases. Corn, sugar beet and rapeseed, on the other hand, are also treated with insecticides . Pickling agents usually have a systemic effect; H. the active ingredient is also transported into new parts of the plant with the sap flow .

history

Dressing seeds is a very old technique; Leek juice was used as a dressing agent as early as 450 BC ; Egyptians, Greeks and Romans used olive pomace , ashes, onion stock or cypress juice to disinfect seeds and thus protect them from pathogens. In the Middle Ages, liquid manure was widely used as a pickling agent. From 1660, seeds were treated with Glauber's salt and copper with moderate success; from 1740 copper vitriol and arsenic preparations and in 1765 the hot water pickle were added. At the end of the 19th century the very effective (but also very poisonous) mercury pickles were developed, which were considered "universal pickles" until the ban in 1982 in Germany. Thus, the seed treatment in 1914 Uspulun introduced in the late 1920s with the Trockenbeize Ceresan was replaced. Since the 1970s, less toxic, but still effective dressing agents from crop protection companies have been on the market. In the 1980s a number of new active ingredients came onto the market ( Bitertanol in 1979 , Triadimenol in 1980 , Pencycuron in 1986 , Fluazinam in 1990 ). In 1991, Imidacloprid , an insecticide stain from the neonicotinoid group, was introduced for the first time .

Active ingredients

In addition to grain, maize and rapeseed, potato tubers and the seeds of some types of vegetables ( onions , carrots ) are also dressed.

formulation

The most frequently used types of dressing are dry dressing ( DS ), wet dressing ( LS ) and suspension dressing ( FS ). Dry pickling is increasingly being replaced by wet and liquid pickling because of its dust development and increased abrasion losses.

Conspicuous coloring

Grain and maize seeds are often denatured against bird damage and colored conspicuously in order to prevent accidental use as fodder or for food.

Pilling

Pilled sugar beet seeds (left) and natural (right)

Pilling is a special form of pickling ; The seeds are surrounded by a layer of pesticides and fertilizers so that each seed has a uniform weight and size. Pilled seeds are suitable for the precision sowing of z. B. sugar beets are necessary so that the labor-intensive chopping to separate the beets in spring can be omitted. The process is labor and resource-saving and in certain respects environmentally friendly, because 100 grams of active ingredient can be enough to treat the seeds for one hectare.
