Why pesticides?

Why pesticides? As a child  I applied Kerosene to control pests eating my plants but unfortunately I lost my plants I learned that pesticides are the solutions ,Today Food production not possible without scientific use of pesticides. Famines like Irish potato famine occurred due to the diseases  affecting potato. In modern era newer and newer molecules are developed to  suit the  needs. It may be fungicide ,weedicide or it may be an insecticide Handle  only after getting expert advice only, because we are answerable to  our newer generations.

FLUBENDIAMIDE

When caterpillars are far beyond economic threshold level affecting your crop what strategy you would take to control the larvae?  A new generation molecule developed against Lepidopteron pests (largest order of insects comprising moths and butterflies.)From our experience larvae of this order, this assumes a major pest of crops not only in rice but vegetables to be controlled most frequently. We used to give our recommendations in the form of application of contact insecticides as we think about chemical method of controlling pests. .Now a new generation molecule, Flubendiamide is found to be useful in controlling larvae of many pests. This insecticide contains Green Triangle mark shows its less toxicity. From experience it is seen that the result of application becomes obvious from third day of application.
