The experiment was designed in  a RCBD consisting of four blocks and three  replicates under each block. The soil pH was  slightly acidic (5-6.5), soil organic carbon was  high (4%) and the soil type was clay. The amount of  cypermethrin found in the soil samples were directly  correlated with the doses applied. In this  experiment, it was found that water has no potential  effect in removing the pesticide residue from the  Chinese kale plants. The degradation time needed to  be degraded 50% of the compound (DT50) was found  from 4 to 5 days and DT90 was found from 17-19 days.  A filter paper acute toxicity test using earthworms  as the test organism was also conducted in the  laboratory condition with the local Thai earthworms  and the median lethal concentration that kills 50%  of the organism (LC50) was found at 1.03 mg\/cm2,  LOEL was observed at 0.001 mg\/ cm2 and the NOEL was  observed at 0.0001 mg\/cm2 of the filter paper.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838368399\"\u003e\u003ch3\u003eA case study of Chinese Kale and soils in Thailand\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838368399","offer_id":39469250478173,"sku":"9783838368399","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/763e2d72-83a5-46d7-91a5-60040918808f.jpg?v=1757827656","url":"https:\/\/shop.autorenwelt.de\/products\/assessment-of-cypermethrin-residue-in-peri-urban-agriculture-von-miah-rahmat-ali","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
