Q

Practice of modifying the growing environment of the plants to make them more resilient against the pest or modifyinh the habitat of the pest to reduce their prevalence.

A

Cultural control

21
Q

Defined as the deliberate alteration of the production system, either the cropping system itself or specific crop production practices, to reduce pest populations or avoid pest injury Tk crops.

A

Cultural control

22
Q

Main purpose of cultural control

A

Make the environment less favorable for the pest and more favorable to the crop and natural enemies.

23
Q

Cultural control can be considered as _______

A

Ecological pest control

24
Q

-Tried and true control technique
-involve one or two or more seasons without the host plant or host contact.
- economical and important in the control of many plant pathogens such as nematodes, bacteria and fungi
- also reduces the population of some insect pests

A

Crop rotation

25
Q

Example of Solanaceae crops

A

Potato, tomato, eggplant and pepper

26
Q

What is the rotation to minimize sweet potato weevil damage?

A

Rotation of sweet potato with squash and corn is recommended

27
Q

What is the rotation to minimize the bacterial wilt of population in the soil.

A

Rotating tomato with corn, string beans and pechay

28
Q

Tillage or cultivation practices can kill pests through mechanical injury, starvation ( via debris destruction) desiccation and exposure.
Eg. Plowing

A

Soil cultivation

29
Q

It kill pests and pathogen propagule, reduce initial insects population or pathogen inoculum for the next cropping season, and destroy wild vegetation (weeds) and volunteer crop plants in and around crop-production habitats.

A

Soil cultivation

30
Q

Keep the soil dry that in direct contact with the root collar of the po lant or may come into contact with low hanging fruit which is subject to infection by soil-borne fungi or bacteria.

A

Shaping the top soil and earthing up or hilling up

31
Q

Causes the damping- off seedlings, basal stem root and wilts.

A

Sclerotium, Rhizoctonia, Pythium, and Phytophthora

32
Q

A special case of multiple cropping
- involves the planting of an attractive small early crop to protect the main crop.

A

Trap cropping

33
Q

Different types of trap cropping arrangements or design

A
  • perimeter trap cropping
    -row TRP cropping
    -strip trap cropping
    Dead-end trap cropping
34
Q

Trap crop surrounds the main crop from all sides
- feasible on small to medium scale areas (too resource-intensive on large scale (seed,time, management)

A

Perimeter trap cropping

35
Q

Planting marigold in a row at the center of rows of tomato to attract thrips early and destroyed.

A

Row trap cropping

36
Q

Planting trap crops in a strip along one common border between two or more crops.

A

Strip trap cropping

37
Q

The trap crop planted in higher densities to capture more eggs of the insects pest and destroyed.
Trap crop planted earlier than main crop

A

Dead-end trap cropping

38
Q

An insect that is attracted to yellow rocket over cabbage, trick is ______

A

Diamondback moth

39
Q

Plants that releases substances in the soil that are toxic.

A

Antagonistic plants

40
Q

It occurs when chemicals release from the plants reduce the population of the pest organism.

A

Antagonism (allelopathy)

41
Q

Example of vegetative planting materials

A

Cutting,stocks,scion,buds,bulbs, tubers, corms

42
Q

Example of disease-free planting materials.

A

Tissue cultured planting materials

43
Q

Practice of growing two or more crops simultaneously in a single field such as multiple cropping, intercropping, multi-storey cropping and companion planting.

A

Habitat diversification

44
Q

It will prevent specific pests to build up the population as rapidly as the case in monoculture cropping. They enhance the activities and survival of natural enemies by providing alternate food sources or refuge for these beneficial insects.

A

Habitat diversification

45
Q

Types of habitat diversification:

A

Multiple cropping
Multiple-storey cropping

46
Q

The ecological conditions to which coconut is adapted are also suitable for growing a variety of fruit and plantation crops, fruits and vegetables underneath.

A

Multiple-storey cropping

47
Q

The one way of minimizing the occurrence of pest.

A

Proper choice of planting site

48
Q

The one way of minimizing the occurrence of pest.

A

Proper choice of planting site
