Kriteria Seleksi Penentuan Ketahanan Kedelai terhadap Kutu Kebul | Sulistyo | Iptek Tanaman Pangan
So far there has been no resistant groundnut genotypes identified as indicated kutk the number of whiteflies observed on each of groundnut genotype whiteflies per accession. Among these varieties, Takar 1 was the most resistant variety to whitefly.
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 that the effectiveness of pest control whitefly infestation can be improved by integrating the use of kutuu varieties with effective insecticide application? Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black.
Plant growth was inhibited. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. One more phenomenon of global warming impact. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant.
Hereinsecticides are applied at the age of 714 with profenos EC. 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. Howeverfive of these varieties have medium and small seeds. The leaves become wrinkled so difficult to distinguish. In this study, the pod yield criteria for resistance to whitefly were set up as follow: Controlled with insecticides or notit still shows the varieties of low yield. Figure 1 Intensity attack B. Title Abstract Author Affiliation.
Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks. In order to maintain the resistance 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.
An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black.
As a resultthe process of photosynthesis of soybean plants running is not normal. The status of whitefly Bemisia tabaci Genn.
To control the leaf -eating pestsBalitkabi doing research. Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. Soybean resistant mechanism to whitefly could be through physical ktuu, such as through the leaf trichomes and leaf thickness.
Mengendalikan Kutu Kebul Bemisia tabaci Gennadius Lewat Kombinasi VUB Kedelai Dengan Insektisida
Abstract Whitefly Bemisia tabaci Genn. All of these viruses are transmitted by insect vectors such as Bemisia tabaci.
Both of these varieties 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. Raya Kendalpayak Kotak Pos 66, Malang Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak.
Not only that, kuti yield loss due to mite attack whitefly B.
If the attack is severeit will cause stunted plantswrinkled leavesand dried up. Figure 3 healthy soybean plants left and the soybean crop pests infestation of B.
The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.
Based on antixenosis mechanism, selection for resistance is kebbul by counting the number of kebyl infestation eggs, nymphs, pupas, adults per leaf area.
