Hereinsecticides are applied at the age of 714 with profenos EC. Soybean Cultivation Technology in Tidal.
Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications.
Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as kegul criteria. To control the leaf -eating pestsBalitkabi doing research. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. As a resultthe process of photosynthesis of soybean lebul running is not normal.
One more phenomenon of global warming impact. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. 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. Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes. Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through kenul leaf trichomes and leaf thickness.
Viral infection of soybean kuut usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
The status of whitefly Bemisia tabaci Genn. In order to maintain the mebul and to avoid the development of new strains of whiteflies, it is suggested that the planting of resistant groundnut should be integrated with selective use of insecticides. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield. Figure 1 Intensity attack B. Both of these varieties have large seeds and leaves oval.
The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy.
In this study, kebyl pod yield criteria for resistance to whitefly were set up as follow: Not only that, the yield loss due to mite attack whitefly B. 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.

kktu Plant growth was inhibited. The leaves become wrinkled so difficult to distinguish. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks.
If the attack is severeit will cause stunted plantswrinkled leavesand dried up. Anjasmoro kitusubsequent varieties are sensitive enough Argomulyo.
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. Title Abstract Author Affiliation. User Username Password Remember me. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Figure 3 healthy soybean plants left and the soybean crop pests infestation of B.
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. Did you know jebul the effectiveness of pest control whitefly infestation can be improved by integrating the use of resistant varieties with effective insecticide application?
Abstract Whitefly Bemisia tabaci Genn. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. Raya Kendalpayak Kotak Pos 66, Malang While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.
Among these varieties, Takar 1 was the most resistant variety to whitefly.
All of these viruses are transmitted by insect vectors such as Bemisia tabaci. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss.
Controlled with insecticides or notit still shows the varieties of low yield. Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Howeverfive of these varieties have medium and small seeds. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look kkutu.
