As a crop of immense importance, garlic is widely grown in different parts of the world. Like every other crop, garlic is also susceptible to various sucking pests such as aphids, thrips, jassids, and whiteflies, which can cause severe damage to the plant. The infestation of sucking pests affects the growth, yield, and quality of garlic crops. Therefore, implementing appropriate control measures is essential to prevent economic losses. In this article, we will discuss the different control measures to combat sucking pests in garlic crops.
Cultural Control
Cultural control is a method that involves the manipulation of the environment for the control of pests and diseases. The following are some cultural control measures that can help in managing sucking pests in garlic crops.
1. Crop rotation: Crop rotation is the best cultural control method to manage sucking pests in garlic. It involves planting different crops in a specific sequence to reduce the build-up of pests in the soil.
2. Proper soil preparation: Appropriate soil preparation, including tilling and plowing, help in exposing the pupae and larvae of the pests to the sun and predators, leading to their eventual death.
3. Sanitation: Regular removal of weeds and debris from the garlic field helps in controlling the population of pests.
Biological Control
Biological control involves the use of living organisms such as predators, parasites, and pathogens to manage pests. The following are some biological control measures that can help control sucking pests.
1. Beneficial insects: Introducing beneficial insects such as ladybugs and lacewings to the garlic field can help reduce the population of sucking pests. These insects feed on aphids and other sucking pests.
2. Natural enemies: Encouraging the natural enemies of sucking pests such as spiders, ants, and birds can also help reduce the population of pests.
3. Microbial control: Microbial control involves using microbes such as Bacillus thuringiensis (Bt) to control sucking pests in garlic crops.
Chemical Control
Chemical control involves the use of pesticides to control pests. It is essential to remember that the use of pesticides should be the last resort. Some chemical control measures for sucking pests in garlic include:
1. Insecticides: Using insecticides such as neonicotinoids, pyrethroids, and carbamates can help control the population of sucking pests. However, care should be taken to use the appropriate method and dosage to prevent harmful effects on beneficial insects and the environment.
2. Acaricides: Using acaricides such as abamectin, diazinon, and fenpropathrin can also help manage mites and jassids in garlic crops.
In conclusion, the control of sucking pests in garlic crops requires the implementation of integrated pest management strategies that involve a combination of cultural, biological, and chemical control measures. Farmers should examine their fields regularly, identify pests’ presence, and then select the most appropriate control measure to manage the pests.
