Question

First: What is the difference between a resistant variety and a resistant original? When are they used in IPM programs with examples?
Second: What are IGRs? And why are they used in IPM programs? And how it works if used in IPM programs
Third: Through your study of the components of IPM programs in protected tomatoes (combating the use of agricultural means or resistant varieties or sterilization
Soil before planting or using biological or chemical control (), answer the following questions:
- How does the IPM program for Butritz disease work on protected tomatoes?
- How does IPM program whitefly fly on protected tomatoes?

Answer 1

First-

Resistant varieties are plants within a certain group that are less vulnerable to attack by plant pests or diseases.

resistance is the reduction of pathogen growth on or in the plant.

In IPM, plant resistance to insects refers to the use of resistant crop varieties to suppress insect pest damage.

Second-

Insect growth regulators (IGRs) are insecticides that mimic hormones in young insects. They disrupt how insects grow and reproduce. IGRs can control many types of insects

Aim of ipm was to conttol pest IGR used as a pest or insect growth regulator

IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce. Because these IGRs work by interfering with an insect's molting process, they kill insects more slowly than traditional insecticides.

Third-

Tomato Cultivation. IPM includes the use of different methods of control viz., cultural, physical, chemical and biological method in as compatible manner as possible to reduce the insect population level below the Economic Threshold Level

The best control for whiteflies is to maximize the distance and time interval between host crops. When possible, plant tomatoes at least one-half mile upwind from key sweetpotato whitefly hosts such as melons, cole crops, and cotton.
