Common diseases and insect pests of Magnolia safflower

The main diseases of Carthamus tinctorius at seedling stage are blight and root rot. Blight mostly occurs in the early stage after the seedlings are unearthed. Because the roots and stems of the seedlings are young and easy to be infected by blight, the control methods of the blight are as follows:

⑴ sprays alcohol once every 10 days with 0.5% ferrous sulfate solution or 1000 times the equivalent Bordeaux solution.

The plants that have been infected by ⑵ can be sprayed with 800 times of Tuijitte solution and sprayed with wine every 7 days for control.

Prevention and control methods of root rot:

After ⑴ seedlings are unearthed, they should be watered less without affecting the growth of seedlings, which is not conducive to the disease.

⑵ immediately excavates the infected plants with soil, and disinfects the soil within 1 meter around the infected plants. The agent can be irrigated with 1000 times of 50% benzoate wettable powder.

Insect pests include small land tigers and grubs, which damage the roots and stems of seedlings.

Prevention and control methods of small land tiger:

⑴ can control weeds and insects to ensure that there are no weeds in the seedling field, and some eggs and larvae can be eliminated.

⑵ fresh grass was trapped and killed, cut short with succulent fresh grass or lettuce leaves, mixed with 99.5 parts of fresh grass and trichlorfon to make fresh grass bait, placed near the seedlings and scattered at a fixed distance to trap and kill larvae.

⑶ medicament control, 50% phoxim EC 1000 times liquid spraying wine seedling field.

Grub control methods:

⑴ black light trapping is carried out before the female adults lay a large number of eggs.

⑵ was sprayed 1000 times as much as 90% trichlorfon in the adult stage.

The main diseases of Magnolia safflower at seedling stage are blight and root rot. Blight mostly occurs in the early stage after the seedlings are unearthed. Because the roots and stems of the seedlings are young and easy to be infected by blight, the control methods of the blight are as follows:

(1) spray 0.5% ferrous sulfate solution or 1000 times equivalent Bordeaux solution every 10 days.

(2) for the diseased plants, the seedlings can be sprayed with 800 times of Tuijitte solution and sprayed once every 7 days for control.

Prevention and control methods of root rot:

The main results are as follows: (1) after the seedlings are unearthed, less watering should be done without affecting the growth of the seedlings, which is not conducive to the disease.

(2) the infected plants were immediately dug up with soil, and the soil was disinfected within 1 meter around the infected plant. The agent could be irrigated with 1000 times of 50% benzoate wettable powder.

Insect pests include small land tigers and grubs, which damage the roots and stems of seedlings.

Prevention and control methods of small land tiger:

(1) weeding and killing insects to ensure that there are no weeds in the seedling field, and some eggs and larvae can be eliminated.

(2) to trap and kill fresh grass, cut the leaves of succulent fresh grass or lettuce short, mix the fresh grass bait with 99.5 parts of fresh grass and trichlorfon, put it near the seedlings and scatter a small pile at a certain distance to trap and kill the larvae.

(3) Pesticide control, 50% phoxim EC 1000 times solution sprayed on the seedling field.

Grub control methods:

(1) Black light trapping is carried out before the female adults lay a large number of eggs.

(2) 1000-fold solution of 90% trichlorfon was sprayed during the occurrence of adults.
