Abstract Induced resistance is an effective measure for controlling plant diseases by utilizing the natural defense of the host and meets the strategic needs of pesticide application and safety for agricultural products worldwide. Ganoderma lucidum polysaccharide (GLP), which is the main active molecule of G. lucidum , has been widely used in functional food and clinical medicine. However, there are few reports of the use of GLP for the prevention and control of plant diseases. The purpose of th...
Lentinan (LNT), a complex polysaccharide with a β-(1→3)-linked backbone of d-glucose residues, has been reported to inhibit plant diseases. Our objective was to explore the efficacy and action mechanism of LNT used as a seed dressing to control sharp eyespot of wheat. Seed dressing promoted wheat growth. At control germination rates of 50%, 8 g of LNT/100 kg of seeds of the Jimai 22, Shannong 23, and Luyuan 502 cultivars significantly increased seed germination to 54%, 52%, and 51%, respectively...

The cereal cyst nematode (CCN, Heterodera avenae) is a major pest in wheat and until now there is no pesticide registered to control this pest in China. Development of effective methods of controlling CCN is urgently needed. Abamectin is a biological pesticide that has a high nematicide activity. However, the efficacy of abamectin soil application to control CCN in wheat and its effect on yield in China remains unknown. Therefore, laboratory, greenhouse, and field tests were carried out to evalu...

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), has evolved resistance to various types of insecticides in the field. In the present study, the resistance of P. xylostella (designated Cya-SEL) to cyantraniliprole increased to 30.6 and 326-fold after 26 generations of selection, compared with the field population (TA) and susceptible population (LAB), respectively. The resistant population also had developed low to moderate levels of resistance to abamectin (3.3-fold), ...

1,3-Dichloropropene (1,3-D) is a potential candidate as a soil fumigant because of the restriction of methyl bromide (MB) in soil fumigation. So far, little is known about the bacteria diversity in 1,3-D fumigated soil. Therefore, the impact of 1,3-D on soil bacterial community was determined by the 16S rRNA gene amplicon 454 sequencing. A total of 230,617 valid reads and 19,366 OTUs were obtained from the thirteen samples. 454 sequencing results revealed that Proteobacteria, Bacteroidetes, Acti...

Southern root-knot nematode (Meloidogyne incognita) is an obligate, sedentary endoparasite of more than 3000 plant species, that causes heavy economic losses and limit the development of protected agriculture of China. As a biological pesticide, emamectin benzoate has effectively prevented lepidopteran pests; however, its efficacy to control M. incognita remains unknown. The purpose of the present study was to test soil application of emamectin benzoate for management of M. incognita in laborato...

The diamondback moth, Plutella xylostella (L.), is considered one of the most damaging lepidopteran pests, and it has developed resistance to all conventional insecticide classes in the field. Chlorantraniliprole is the first commercial insecticide that belongs to the new chemical class of diamide insecticides. But, P. xylostella have already shown resistance to chlorantraniliprole in China. After 52 generations of selection with chlorantraniliprole, ∼48.17-fold resistance was observed. The resi...

BACKGROUND Fluopicolide, a novel benzamide fungicide, was registered for control of oomycete pathogens, including Phytophthora capsici. In this study, fluopicolide (5% SC) was applied in soil at rates of 1.5, 3 and 6 L ha−1 [the normal (ND), double (DD) and quadruple dosages (QD) respectively] to investigate its transportation behaviour and control efficiency on tomato blight as a soil treatment agent. RESULTS The results showed that fluopicolide applied to soil could be absorbed by tomato roots...

ABSTRACT Silkworm (Bombyx mori) is an economically important insect and an ideal nontarget organism to study the environmental assessment of pesticides. Two acute toxicity test methods, leaf-dipping and quantitative spraying, with five insecticides, were compared for pesticide risk assessment. Based on LC50 values of these insecticides by both methods, the order of toxicity levels of five insecticides tested against silkworm was as follows: emamectin benzoate>lambda-cyhalothrin>imidacloprid>chlo...
