Special Issue Information

Dear Colleagues,

Vegetables are important economic and horticultural crops. However, during the growing period of vegetables, a wide range of diseases and insect pests on the vegetables cause giant economic losses. Especially with the increase in the number and size of protected cultivation areas, relatively stable conditions in the greenhouse make those diseases and insect pests heavier and more complex. Learning how to control those harmful organisms efficiently is the main concern of vegetable growers.

The purpose of this Special Issue on “Integrated Disease and Pest Management of Vegetables” is to present recent studies on some of these concerns, such as innovative studies, approaches, and techniques that have been successful in addressing some of these concerns, such as the occurrence of diseases and insect pests, pesticide resistance, physical control, biological control, chemical control, integrated management, and any other innovation that has improved the control efficiency of diseases and insect pests on vegetable crops.

Insect vectors and insect-borne plant viruses seriously endanger the safety of agricultural production. An insecticide is one of the main methods to prevent insect-borne virus transmission. However, the curious relationship between the resistance of insect vectors and arboviruses has been less studied. In this study, the effect of Tomato chlorosis virus (ToCV) on the insecticide resistance of Bemisia tabaci MED was studied. It was found that the detoxification cytochrome P450, glutathione S-transferase, and carboxylesterase-related genes in ToCV-infected B. tabaci were upregulated. The activity of the three detoxification enzymes all increased at the same time, after 48 h of virus acquisition, with the activity of carboxylesterase being the most pronounced. It was found that cytochrome P450 and glutathione S-transferase activity was the least. ToCV led to the reduced sensitivity of B. tabaci MED to pyrethroids and flupyradifurone. Therefore, it was proven that the insect-borne plant virus ToCV shows the possibility of enhancing insect-borne insecticide resistance. Full article

Tomato gray mold (TGM), caused by Botrytis cinerea, is a destructive disease of greenhouse tomatoes. Its control mainly depends on the application of chemical fungicides. In China, penthiopyrad has been registered for the management of TGM for about 3 years. In this study, the baseline sensitivity of B. cinerea to penthiopyrad was measured based on mycelial growth and spore germination, using 131 wild isolates collected from Hebei Province. The mean EC50 values 1.054 ± 0.633 mg/L (on mycelial growth) and 0.101 ± 0.037 mg/L (on conidia germination) were used as the baseline sensitivity. Isolates (187) of B. cinerea, sampled from eight regions in Hebei province during 2021 and 2022, were used for resistance studies by mycelial growth method. Based on the resistance factor, these isolates were considered: sensitive (=65 isolates), low (=39 isolates), moderate (=38 isolates), and high (=45 isolates) resistance. All 15 isolates from Raoyang were sensitive to penthiopyrad. Four mutation types in the sdhB subunit, namely H272R, N230I, P225F, and P225L, were associated with the resistance to penthiopyrad. A positive cross-resistance was also recorded between penthiopyrad and fluopyram, boscalid, or pydiflumetofen. These results provide useful information on the chemical control of TGM. Full article

The two-spotted spider mite, Tetranychus urticae, is an important pest of horticultural crops worldwide and has developed resistance against multiple kinds of pesticides. To date, information on the resistance to pesticides is inadequate for T. urticae populations in Hainan, south China. In the current study, we determined the resistance to seven pesticides in five field populations of T. urticae that were collected on cucurbit crops in Hainan in 2021. The results showed that T. urticae populations developed high to extremely high resistance to abamectin and bifenthrin and medium to high resistance to pyridaben, profenofos, and cyflumetofen. However, four of the five populations were either susceptible to or had only low resistance to bifenazate and B-azolemiteacrylic. We also determined the frequencies of mutations previously associated with T. urticae resistance to abamectin, pyrethroids, organophosphates, bifenazate, or pyridaben; mutation frequencies as high as 100% were detected for some of the mutations in some of the populations. The results should facilitate the development of rational strategies for the chemical control of T. urticae populations in Hainan, China. Full article

Fusarium oxysporum f. sp. conglutinans (FOC) is the dominant pathogen of vascular wilt disease on cabbage and other crucifers. Foc-Nto1 was confirmed to be the homologous protein of Nto1, a subunit of the NuA3 (nucleosomal acetyltransferase of histone H3) complex in Saccharomyces cerevisiae. FOC contains two races, race 1 and race 2. The functions of Nto1 in both races were investigated through functional genetics analyses. The Nto1-deleted mutants were decreased in conidium production and displayed increased sensitivity to hydrogen peroxide. These mutants also had reduced virulence on cabbage. The study provided evidence that Nto1 is a potential metabolic- and pathogenic-related factor in F. oxysporum. Full article

The common cutworm, Spodoptera litura (Fabricius), is a notorious and damaging insect pest of horticultural crops in China, the management of which largely relies on chemical agents that are limited by the development of chemical resistance in target populations. As such, resistance monitoring of S. litura populations is a necessary part of management strategies of insecticide resistance. In the current work, we monitored resistance to six insecticides in field-collected populations of S. litura sampled from eleven provinces across China in 2021. The results show that S. litura populations developed significant resistance against chlorantraniliprole, cyantraniliprole, metaflumizone, and pyridalyl and low levels of resistance to chromafenozide. However, S. litura populations were susceptible or exhibited minimal resistance to tetraniliprole. Possible cross-resistances between chlorantraniliprole, cyantraniliprole, metaflumizone, pyridalyl, and chromafenozide were found by pairwise correlation, which also revealed that tetraniliprole lacked cross-resistance with all insecticides tested. Our results suggest suspending the use of chemical agents against which S. litura displayed significant field-evolved resistance, such as chlorantraniliprole, metaflumizone, and pyridalyl, in favor of pesticides against which S. litura was susceptible or exhibited minimal resistance, such as tetraniliprole and chromafenozide, which may help slow the development of insecticide resistance, and in which field management programs aimed at controlling S. litura in China would benefit from the integration of such survey-informed insecticide application strategies. Moreover, the baseline susceptibility confirmed for the six tested insecticides can contribute to design strategies of resistance management for S. litura. Full article

Turnip mosaic virus (TuMV) is an important threat to the yield and quality of brassica crops in China, and has brought serious losses to brassica crops in the Far East, including China and the north. Aphids (Hemiptera, Aphidoidea) are the main mediators of TuMV transmission in field production, and not only have strong virus transmission ability (small individuals, strong concealment, and strong fecundity), but are also influenced by the environment, making them difficult to control. Till now, there have been few studies on the resistance to aphids in brassica crops, which depended mainly on pesticide control in agriculture production. However, the control effect was temporarily effective, which also brought environmental pollution, pesticide residues in food products, and destroyed the ecological balance. This study reviews the relationship among brassica crop–TuMV, TuMV–aphid, and brassica crop–aphid interactions, and reveals the influence factors (light, temperature, and CO2 concentration) on brassica crop–TuMV–aphid interactions, summarizing the current research status and main scientific problems about brassica crop–TuMV–aphid interactions. It may provide theoretical guidance for opening up new ways of aphid and TuMV management in brassica crops. Full article
