The main mechanism of resistance in A. fumigatus involves incorporation of tandem repeats in the promoter region of cyp51A, along with point mutations in the gene sequence. Resistant isolates tend to arise either due to excessive use of azole fungicides in the agricultural fields, from where they reach human through sporulation; or by prolonged treatment of patients with azole drugs. The early diagnosis of aspergillosis is very crucial for successful treatment of a patient.

The aim of this study was to evaluate the antimicrobial activity of three commercial GSE (Grapefruit Seed Extract) products against six bacterial and one fungal strain, through the agar well diffusion method, determination of minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC). Obtained results indicate strong antimicrobial effects of investigated extracts, with different microbial susceptibility, including the multidrug-resistant (MDR) bacteria.

Penicillium italicum (blue mold) is one of citrus pathogens causing undesirable citrus fruit decay even at strictly-controlled low temperatures (< 10 °C) during shipping and storage. P. italicum isolates with considerably high resistance to sterol demethylation inhibitor (DMI) fungicides have emerged; however, mechanism(s) underlying such DMI-resistance remains unclear.

The fungicide fludioxonil over-stimulates the fungal response to osmotic stress, leading to overaccumulation of glycerol and hyphal swelling and bursting. Fludioxonil-resistant fungal strains that are null-mutants for osmotic stress response genes are easily generated through continual sub-culturing on sub-lethal fungicide doses.

Common scab caused by Streptomyces scabies (Thaxter) Waksman & Henrici is an important disease worldwide, and can cause significant reduction in the economic value of potato. The management of the disease can be done through conventional methods, biological chemical and cultivation of resistant variety. However, resistance against pathogen is not a permanent solution and fungicidal is not ecofriendly and economical. But new search, induce resistance has taken great attention for plant disease management in near future.

Trichoderma spp. are tolerant and compatible with fungicides, biofertilizers and other bio pesticides. Integrating fungicide resistant antagonists with suitable fungicide treatment has importance in the frame work of integrated disease management. Incorporation of natural products provides a viable solution to the environmental problems caused by synthetic pesticides. Identification of these compounds and their further testing may be an effective approach to minimize the use of hazardous chemicals

Black gram anthracnose caused by Colletotrichum lindemuthianum is the most devasting disease. Due to its severe infection during humid climatic conditions spraying of chemical fungicides is essential to control the disease. Frequent application of synthetic chemicals, leads to the detoriation of environment and development of resistance. The present study was carried out to manage black gram anthracnose pathogen using plant extracts.

Turcicum leaf blight (TLB) or Northern Corn Leaf Blight (NCLB) is a ubiquitous foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria. The TLB fungus survives through the winter on infected maize residue at the soil surface. As temperatures rise in the spring and early summer, the fungus produces spores on residue, and then the spores are splashed or wind-blown onto leaves of the new maize crop. Infection occurs during periods of moderate (64° to 81°F), wet and humid weather.

Maize is the 3rd most important crop in the Bihar next to rice and wheat. It is grown throughout the year in one or other part of state. Due to continuous cropping of maize and other factors like improper use of fertilizers, pesticides and climate change, the disease problem has increased in tremendous proportion. Almost all parts of the maize plant are susceptible to numerous diseases that considerably reduce the yield and quality of the crop.

A field experiment was conducted during Kharif 2017-2018 to study the effect of tropical red seaweed (Kappaphycus alvarezii) bioformulations (LBS 6 and LBD 1 in relieving the fungicidal stress and imparting the resistance to blast disease) in rice. Foliar application of LBS6 @ 1 ml/l was found to be statistically superior in improving yield parameters viz., straw (6.94 kg/plot) and grain weight (5.59 kg/plot).

Occurrence of root rot disease has become a major constraint in recent years for successful and profitable cultivation of chickpea. The efficacy of Bio-agent viz. Tricoderma viride, Organic amendment viz. neem cake, Plant extract, garlic, and Fungicide, Carbendanzim applied through seed treatment and soil application were evaluated against Macrophomina phaseolina causing root rot disease of Chickpea.

The brinjal variety Hisar Shyamal (H-8) is popular among farmers in the state of Haryana and neighbouring states of India. It experiences huge losses in fruit yield as it is not resistant to devastating seed borne diseases viz. damping off and fruit rot caused by Phomopsis vexans in addition to other mycoflora. Seed treatment with chemical fungicides like carbendazim is a common practice to control these seed borne diseases of brinjal. However, continuous use of these chemical fungicides are not safe both environmentally and human health point of view.
