seed-borne pests interception

post entry quarantine

plant pathogens are intercepted by

insect pests are intercepted by

applicable to fungi, bacteria, nematodes

this can adversely affect the pest present in the stubbles and in the soil

once resistant varieties are available, this practive is the easiest and the most effective to implement. It is considered safe to the end users/consumers and does not pollute the environment

this strategy prevents the introduction of any pest in the area where taht pest is not yet present or have not yet established. Also reduce the sourfce of the pest at the start of the cropping season

This is one way of starvng the pest by breaking the continuity of food supply, However, care must be undertaken in such a way that the crop to be grown in succession is no the alternated host of the pest attacking the crop grown in the previous season

This is necessary to either delay or advance the planting of the crop so that the susceptible stage of the crop will not coincide with the peak population of the pest.

removal of possible harborers of pest or alternate host through the removal of crop debris from previous cropping season

for ease in cultivating and weed and to improve the microclimate of the crop which is unfavorable for the pathogen

prevents the transfer of pests from one leaf to another in case of overlapping branches, also affect the microclimate

this avoids competition between plant s and improce microclimate of the crop that will not be favorable

to encourage natural enemies because each crop has its own pest and that pest has its own natural enemies so the attention of the pest spread out, pest damage is lesser compared to monoculture cropping

planting a susceptible crop or host earlier than the main crop to attract pest like insect and nematodes and destroying them by chemical or physical means before they can reproduce thus reducing pest populaton before the crop is planted

trap crops used in exp. 2

used to kill the nematodes in exp. 2

any plants that does not compete with crop, and brings greater balance and diversity than monocrop by attracting natural enemies or by repelling pests

used as mulches

a bait used for rodents

a trap for rodents

used to communicate, locate food source or a mate, escape natural enemies, avoid competition, or overcome a natural defense system of a host
