Summary
An extension program successfully increased grower adoption of insecticide resistance management (IRM) practices for onion thrips. Growers adopted insecticide class rotation and action thresholds, driven by concerns over resistance development.
Area of Science:
- Agricultural Entomology
- Pest Management
- Sustainable Agriculture
Background:
- Insecticide resistance management (IRM) is crucial for sustainable agriculture, yet adoption challenges persist.
- Few studies evaluate the effectiveness of voluntary programs in promoting IRM practices.
- Onion thrips (Thrips tabaci) pose a significant threat to onion production.
Purpose of the Study:
- To assess the effectiveness of a voluntary, extension-based program on grower adoption of IRM practices.
- To evaluate the impact of the program on insecticide use and pest control for onion thrips.
- To understand grower motivations for adopting IRM strategies.
Main Methods:
- A 3-year study involving 17 onion growers.
- Implementation of an extension-based program promoting insecticide class rotation and action thresholds.
- Monitoring of grower adoption rates and insecticide application practices.
Main Results:
- Grower adoption of insecticide class rotation increased from 76% to 100%.
- Adoption of action thresholds rose from 57% to 82%.
- Consistent use of action thresholds led to fewer applications and reduced costs ($148/ha less).
Conclusions:
- The extension program successfully increased IRM practice adoption within 3 years.
- Growers prioritized mitigating insecticide resistance over cost savings.
- Interactive extension programs can enhance the adoption of IRM and integrated pest management tactics.

397
An increasing function exhibits a rise in output values as input values increase. This behavior is depicted graphically as a curve or line that slopes upward from left to right. Such a function satisfies the condition that if x1 < x2, then f(x1) < f(x2), indicating that the function values grow with increasing inputs. This concept is fundamental in understanding growth trends across various domains, such as population dynamics, financial investments, or resource consumption.The...

01:25Increased Body Temperature
7.5K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

01:22Resistivity
4.6K
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

01:19Resistance
6.0K
When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...
