How to control pests and diseases?

(1) Use decomposed feces to avoid the temptation of immature feces and evil underground pests.

(2) Deep ploughing can not only kill some pests directly, but also facilitate birds to eat some pests.

(3) Spring irrigation and autumn irrigation can not only directly drown some pests, but also inhibit the activities of other pests.

(4) Remove the weeds around the ridge and reduce the insect source and pathogenic host.

(5) Choose a plot with high terrain and good drainage to carry out experiments to avoid diseases caused by humidity.

There are many kinds of forage grass, and the test site may undertake the task of forage grass test that has never been planted in local production or previous experiments. On the basis of carefully studying the test plan and mastering the technical points, the test site should make preparations in advance, focusing on preventing some sudden pests and diseases that may be caused by this forage. After finding pests and diseases, you should contact the local plant protection department or relevant scientific research units for diagnosis and early prevention to avoid serious impact on the experiment.
