WHITE-WASH - Controlling of White Fly (Bemisia Tabaci)

White Fly is one of the most irritating to protected crops. They suck up large amounts of sap from the plant and secrete the sugars as honeydew. This unfortunately makes the leaves sticky and susceptible to rot and attacks by fungus. These pests affect all types of plants including both crops and ornamental plants, both indoors and out. These pests have also been known to carry viruses, which poses an even greater threat. 

The greenhouse White fly crawler has four or possibly five leg segments and 2-3 antenal segments. Segmentation is not clear and most specimens will appear to have only three leg segments and two antennal segments. The crawler may be transparent to opaque, ranging in color from light green to yellow, light brown through dark brown and black. 

Small amounts of powdery white wax are usually produced after the crawler settles and begins feeding. The pupal cases of this species can vary depending on the leaf surface (Glabrous vs. hairy). Feeding by the adults and larvae on the underside of leaves from June to late autumn causes white or yellow patches to develop. Yellow eggs are laid in circular groups on the underside of leaves. Within a few days the eggs turn black, before hatching in about nine days at temperatures of around 21°C. Light green, flat larvae are only active for a few days and then remain motionless until they reach maturity. 

White flies pass through four life cycle stages before reaching adulthood. Adults are covered in a white, mealy wax and only grow to about 1 mm in length. Feeding on plant sap is achieved via stylets, much the same as with aphids.

Damage :

Feeding white flies will cause leaves to turn up and brown, disabling them to perform their responsibilities. Damaged leaves look bad and promote decay fungus and bacteria to form Sap drainage. White flies have an insatiable hunger for plant sap and will suck as much of it as they can from the host plant. Young host plants will not be able to meet these demands and don't stand much of a chance to survive; adult plants which loose vital sap are more prone to disease, heat stress and less likely to rebound from any environmental shock. This pest is a vector of Lettuce infectious yellow virus.

Host range :

The host range of the greenhouse White fly is estimated at about 200 plant species, mostly in the families crucifereae, Leguminosae, Malvaceae, and Solanaceae. The insect may attack far more plant species in the greenhouse environment. 

Dosage :

1-2 ml/ Liter of  water as foliar application on the occurring of pest


Packing: 

100 ml/250 ml/500 ml/1 Ltr.
