By sucking the fluid from inside the network carrier rice brown plant hopper can cause mild to seve

Brown planthopper (Nilaparvata lugens) is still regarded as a major pest in rice crops due to damage caused quite widespread and occur in almost every cropping emu oil season.
The use of pesticides emu oil in violation of the rules of IPM (right kind, the right dose and the right time of the application), which triggers the explosion BPH. It is also a consequence of the application of the system of rice intensification (high yielding varieties, high doses of N fertilizer, application of IP> 200 and so on). Depending on the extent of damage, brown planthopper attack can increase rice yield losses of only a few hundred pounds of grain to puso.
Damage caused may occur directly or indirectly. Directly due to the ability of the brown planthopper insects suck plant tissue fluids so that the rice plants become dry and eventually die. Indirectly because the brown planthopper insect vector disease virus can be stunted and stunted grass hollow.
By sucking the fluid from inside the network carrier rice brown plant hopper can cause mild to severe damage in nearly all phases of growth from seedling phase, tillers, cook until the milk phase (charging).
Symptoms that appear from BPH attacks can be seen from the leaves turn yellow and then the plants dry out quickly (like burning). This phenomenon is known as hopperbum. In a stretch of symptoms hopperbum seen as a form of a circle that shows the pattern of spread of the brown planthopper which starts from one point and then spread out in all directions in the form of a circle. In such circumstances, the population of brown planthopper is usually very high.
Preventive measures emu oil coklatsecara planthoppers generally be done by using variatas resistant, rice cultivation simultaneously with a spacing that is not too tight, varieties and rotation control with insecticides.
But by looking at the symptoms of damage caused to the paddy rice field mapped to result in losses that are not small, then the eradication of this pest needs to be done by way of preventive, curative and repressive.
Cropping patterns simultaneously in large areas and are not limited by administrative boundaries can anticipate the spread of the brown planthopper attack because if not simultaneously pests can move into rice fields that have not been harvested. BPH can not be prevented from migrating fly by rivers emu oil or oceans.
Observation or monitoring of brown plant hopper every 1-2 weeks. If there is a clump of rice leaves wilt perform the checks emu oil carefully. If found a rice planthopper dirumpun immediately kill / destroy and check its eggs on the leaves and the leaves are removed and burned. If the observation emu oil of the brown planthopper per clump exceeds the immediate economic threshold control with insecticides.
Light traps are the most common emu oil traps used for monitoring insect migration and population estimates are particularly interested in the light brown planthopper. The things that need to be considered in the use of light traps among others; contrast of light used (the contrast of light bulbs that are used the more extensive range of catch), the ability of insects to avoid the traps light and light intensity (in general seranga tend to gravitate towards emu oil high light intensity).
Light traps installed on the bund (place) that is free from shade to a height of about 1.5 meters above ground level. The light used is 40 watt incandescent bulb with a voltage of 220 volts. Lights switched on at 18.00 and off at 06.00. So that insects do not fly anymore then caught the insect reservoir containing a small amount of water added.
Steps taken after the hopper is light traps; leafhoppers were caught buried, dry rice cropping up cracked and dried immediately after planthopper control on rice plants with insecticides recommended (curative actions).
Curative action is brown planthopper pest control measures by using a recommended insecticide. This action is not a step but a step further preventive emu oil eradication. This step can be done by using the insecticide active ingredient buprofen, BPMC, fipronil, amitraz, bupofresin, carbofuran, karbosulfan, metalkarb, MIPCI, propoksur or liarnetoksan and imidacloprid.
The use of insecticides in the form of powder / granules emu oil (eg Furadan, Basudin, diazinon) is done by sprinkling rice terraces between the bolt 3 or 4 weeks. Liquid insecticide spraying emu oil is done once a week or a maximum of 10 days. All use of insecticides should pay attention to the rules and wear dosage listed on each product emu oil used.
