PROTECT POPLAR PLANTATIONS AND NURSERIES FROM THE ATTACK OF POPLAR LEAF DEFOLIATOR: PAU

LUDHIANA, JULY 22:



According to the entomology experts of the Punjab Agricultural University (PAU), the poplar plantations and nurseries have been infested with poplar leaf defoliator, Clostera fulgurita and Clostera cupreata during the last fortnight. The attack has become serious in the last few days and is resulting in severe defoliation of nurseries and plantations throughout Punjab, particularly, in the riverine belts (Bet areas), informed Dr Balwinder Singh, Head of Entomology Department, PAU. The peak activity period of this defoliator is July and October, he cautioned. About its symptoms, Dr Singh told, "The attack can be identified by observing black excretal pellets of the larvae on the ground and also by noticing the leaves which are either skeletonized or completely eaten away. The larvae feed on the green tissue of the leaves, leaving behind the veins only."



Giving preventive advisory, Dr Singh suggested the farmers that the defoliator can be controlled by spraying the nurseries and plantations with Quinalphos 25 EC @ 4 ml/lt or Profenophos 50 EC @ 2 ml/lt using 250-300 litres of water per acre. The spray should be done with tractor operated sprayer in 3-5 year plantations or with foot sprayer or rocking sprayer in case of 1-2 year old plantations and nurseries, he emphasized.
