BPH : A FLYING PERIL
Numerous species of planthoppers are found in agriculture, and many of them have a broad host list (for example, the potato leafhopper, Empoasca fabae, has over 100 host plants). They feed on foliage and shoots of many different plant species by piercing the plant cells and sucking out the contents. The damage that results from feeding depends on the host plant and the specific hopper. Only a few species of hoppers transmit pathogens such as those that cause curly top virus and aster yellows. Adult hoppers are excellent short-distance jumpers when disturbed, and they can be pests when found in high numbers.
Planthoppers look a lot like Leafhoppers, but they have fewer leg spines and more interesting heads. Their bodies are shaped like wedges or half-circles. They and bright green and resemble leaves, even down to the ‘veins’. They are agile jumpers and leap from plant to plant to feed on them. They also quickly hop away from perceived danger. Adults feed on the juices of plants. A tropical species from the some family was thought to glow in the dark and were hence called Lanternflies, but none of these insects are luminous. The some stuck despite the fact.
The damage by planthoppers is estimated to cause a yearly loss of about 100 tons in agricultural crops, despite all the currently used methods for planthoppers control! For cereals alone it is estimated that farmers could lose around 5% of their crop due to planthoppers infestation, that number can reach 40% when it comes to some of our staple crop such as wheat and rice. There are around 12,500 distinctive planthoppers species known. The most harmful planthoppers in agriculture are the BPH and WBPH.
Brown Planthopper (BPH) :
The brown planthopper is a sucking insect that, under heavy infestations, can cause the wilting and complete drying of rice plants, a condition known as ‘hopperburn’ . The brown planthopper also damages rice by transmitting ragged stunt virus and grassy stunt virus. The insect can complete as many as 12 generations in a single year in tropical areas, where it resides year-round, and fewer generations in temperate areas, where it is a migratory pest.
White backed planthopper (WBPH) : WBPH is one of the most important sucking pests in India in many rice growing tracts. Some of the factors responsible for severe infestaton levels are introduction of high-yielding but susceptible varieties (HYVs), high input use especially use of nitrogenous fertilizers and use of broad spectrum synthetic pesticides. Serious incidence of WBPH coincides with maximum tillering stage with appearance of ‘hopper burn’ symptoms towards crop maturity stage. WBPH nymphs and adults are found on the upper portion of the stems, with the majority at the junction between leaves and stems. Both nymphs and adults suck sap and actively multiply under congenial weather conditions. Planting time, which is dependent on the incident rainfall or water availability for irrigation has a significant bearing on the timing of initial population, its build-up and coincidence with susceptible crop growth stage with conducive temperatures and relative humidity. Temperature is a key driver of WBPH development, survival and reproduction.
HPM has such huge numbers of products which provide the complete protection from planthoppers. For the advancement of ranchers organization is giving them the best quality insecticides,fungicides, herbicides and plant growth regulators . HPM have products like 7-Star, Hitatox, Hindol, Hi-Imida and Gajini. These products have unique chemical properties , which result in excellent control of many species of planthoppers. Use of these products paralyse the pest, which remain immobile on the crop until death in about 3-4 days. These products are economical to use as single application provides effective pest control.
At HPM we do trainings in various states to fabricate the care and finding out about the planthoppers and give information about the accessible arrangements. We are successfully connected with instruction drives concerning spreading mindfulness about upgraded and better cultivating rehearses. We offer through and through advice and workshops to agriculturists on how and when to use insecticides.
