Against common diseases and insect pests of pumpkin and bitter gourd with, but also spread disease and Liriomyza solani.
1, spreading blight
(1) and non-melon crop rotation of 2-3 years to implement;
(2) with 2.5% SC Celest seedvax: seeds per kg with 2-4 ml of Celest, methods in the light of article 4 Dongguashan wilt;
(3)cultivation, mulching, to strengthen the exclusion of water during the rainy season;
(4) can be used to prevent blight spread Amistar 25% SC 1500 times, with the first two methods to combat the disease with palmi;
(5) growing emphasis on prevention and treatment centers do a good job before the incidence of morbidity period of medication, should be used in the treatment of smoking fungicides, such as 10% of the world of high WG 1500 times, spraying once every 7-10 days, continuous 2-3 times. When dispensing drugs must first be opened into a mother liquor, and then poured into the sprayer, so that uniform liquid concentration. With 40% SC Granville 500 times, or 21.2% WP additional heat will be 1000 times, 2000 times encyclopedia EC, 50% carbendazim WP 500 times, 25% of the enemy force times from the turn of 1500 EC use, every 7-10 days, 2-3 times Liaison. 40% can also be used Granville SC 500 times increase of 50% WP Carbendazim 500 times mix flour coated stem.
2, Liriomyza sativae
(1) the elimination of post-harvest plant residues, concentrated burnt or buried deep stack ret;
(2) appropriate, sparse leaves, remove the lower part of the leaf insects Road in order to reduce the insect population base;
(3) field settings "sticky fly paper"; adult peak in Plant 2 / 3 height of the bamboo fence put "sticky fly paper" (if at this time for the full flowering stage, they have to strengthen the artificial pollination), per 15 -- 20 points, once every 15 days to stick to kill an adult, lower population density;
(4) chemical control; seize the peak in larval spraying, spraying of 1.8% can be extremely harmful EC 3000 times out, or 1.8% EC love Fording 1000 times, 40.7% Chlorpyrifos EC 1000 times, 90 % padan WP 1200-1500 times, 90% WP monosultap 800 times, alternating the use of every 7-10 days for 2-3 times.
