Garlic root and bulb pests include:
Seed maggot control methods: First, for fields where a small number of seed maggots have been found causing damage, switch from applying various types of manure to applying refined organic compound fertilizer. For example, bio-organic compound fertilizer containing humic acid bacteria, etc., or apply multi-element compound fertilizer; Second, use Dithane granules at 800-1000 g/667 sq m, mix with fine soil to make poisonous soil, and broadcast or apply in furrows at the root zone; Third, use 40% Carbens emulsifiable concentrate at 200-250 g, diluted with 200 kg of water to drench the roots; Fourth, where water sources are sufficient, irrigate continuously 2-3 times, each time soaking for 24 hours, so that the seed maggots suffocate and die, then drain the water as soon as possible.
Root mite control methods: Spray with 40% quick-acting parathion emulsion at 1000 times dilution, or mix 70 ml of quick-acting parathion with fine soil to make poisonous soil and apply in furrows; the latter is the dosage for 667 sq m.
Stem nematode control methods: First, spray with 40% quick-acting parathion emulsifiable concentrate at 1000 times dilution to kill them; Second, use Dithane granules at 800-1000 g/667 sq m mixed with fine soil to make poisonous soil and broadcast.
Manure fly control methods: First, carry out careful intertillage and weeding to create an environment with loose soil and no weeds, inhibiting egg hatching and larval activity; Second, drench the roots with 50% phoxim emulsifiable concentrate at 800 times dilution to kill the larvae, or use 40% Carbens emulsifiable concentrate at 200-250 g/667 sq m diluted with 200 kg of water to drench the roots.
