As a resultthe process of photosynthesis of soybean plants running is not normal. In this study, the pod yield criteria for resistance to whitefly were set up as follow: The status of whitefly Bemisia kuut Genn. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.
IPI Prospek Varietas Toleran dalam Pengendalian Hama Kutu Kebul pada Kacang Tanah : View Article
Hereinsecticides are applied at the age of 714 with profenos EC. Both of these kbul have large seeds and leaves oval. Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. In order to maintain the resistance and to avoid the development ,utu new strains of whiteflies, it is suggested that the planting of resistant groundnut should be integrated with selective use of insecticides.
Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes. So far there has been no resistant groundnut genotypes identified as indicated by the number of whiteflies observed on each of groundnut genotype whiteflies per accession. Figure 1 Intensity attack B. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo.
User Username Password Remember me. Selection of resistant soybean based on tolerance mechanisms was done kebyl observing the decrease in grain yield due to whitefly attacks.
Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.
Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. Did you know that the effectiveness of pest control whitefly infestation can be improved by integrating the use of resistant varieties with effective insecticide application?
To control the leaf -eating pestsBalitkabi doing research. Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black.
The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable ,utu. Howeverfive of these varieties have medium and small seeds. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.
In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Title Abstract Author Affiliation.
Unless the varieties Anjasmoro sensitive whitefly pest infestation. Soybean Cultivation Technology in Tidal.
If the kebjl is severeit will cause stunted plantswrinkled leavesand dried up. Antibiosis mechanism was selected by observing the life cycle of whitefly, including the duration of the hatching eggs into nymphs, the development of the nymph into pupa, and the adult insect emergence. Chemical control to the pest has not produced satisfactorily results, and even has given a negative impact on the environment, damaging the efficacy of biological agents, and causing resistance to chemical compounds on whitefly.
Controlled with insecticides or notit still shows the varieties of kjtu yield. Raya Kendalpayak Kotak Pos 66, Malang Nymphs and adults of whitefly are jutu stages that cause damage directly or indirectly on the host plant.
Worse yetkytu whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria.
Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Among these varieties, Takar 1 was the most resistant variety to whitefly.
Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. One more phenomenon of global warming impact. The leaves become wrinkled so difficult to distinguish. Evaluation of groundnut for resistant germplasms had been carried kebkl with resistant criteria as a basis for the assesment. Plant growth was inhibited.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as kitu the leaf trichomes and leaf thickness. Not only that, the yield loss due to mite attack whitefly B. All of these viruses are transmitted by insect vectors such as Bemisia tabaci. Abstract Whitefly Bemisia tabaci Genn.
In addition to directly damaging cropsalso a whitefly infestation of insect vectors that can transmit disease virus Cowpea mild mottle virus CMMV on soybeans and other legumes.
