Cov kev ceev faj
(1) Tsis txhob nce ntau npaum li cas thiab ntau zaus ntawm daim ntawv thov ntawm qhov xav tau, thiab xyuam xim rau kev siv lwm yam nrog cov tshuaj tua kab uas tsis yog pyrethrin.
(2) Tsis txhob sib xyaw nrog cov tshuaj alkaline xws li Bordeaux sib tov.
(3) Nws yog ib qho tshuaj lom heev rau cov kab mob hauv dej, muv, thiab kab laum, yog li yuav tsum tau saib xyuas kom tsis txhob muaj kuab paug hauv dej thiab muv thiab cov kab kab kab sib chaws thaum siv.
(4) Nws yuav tsum tau muab khaws cia rau hauv qhov chaw txias thiab qhov cua, kom deb ntawm qhov hluav taws kub thiab qhov cua sov, tiv thaiv tshav ntuj ncaj qha, thiab khaws lub ntim kom nruj.
