Eight cotton cultivars, with and without aldicarb treatment, were evaluated for their effect on the severity of the root-knot nematode-Fusarium wilt disease complex in cotton. A randomized complete block design with a split-plot arrangement of treatments was used with cotton cultivars as the main plots and nematicide treatments as the subplots. Results in 1994 and 1995 were similar. Yield of lint, boll weight, and wilt and root-gall ratings were different among cultivars and between nematicide treatments both years. Increased lint yield and boll weight, and reduced root-gall and wilt ratings were associated with application of aldicarb. Increased lint percentage was associated with application of aldicarb in 1994, but not in 1995. Fiber micronaire, elongation, uniformity, and strength were different among cultivars, but not between nematicide treatments. Fiber length (UHM; Upper-Half Mean) was different among cultivars and was higher in the aldicarb-treated plots in both years. Numbers of Meloidogyne incognita second stage juveniles and eggs extracted from soil samples were lower in the aldicarb-treated plots in July, but not at harvest, both years. Population densities of M. incognita were not different among cultivars, except the mid-season sample in 1995.

This research was conducted in Pante Cermin, Padang Tiji Subdistrict, Pidie District. in March to August 2015, with the aim to know the use efficienci of Trichoderma sp on the growth of several types of Banana seedlings (Musa Paracica L.) This research using Randomized Block Design (RAK) factorial pattern with the factors studied is the type of banana and trichoderma dose . Both factors consist of 4 levels: Banana Barangan (J1), Ambon banana (J2), Banana King (J3) and Geupok banana (J4). While the dose of Tricoderma sp is: TO = 0 g / seeds T1 = 15 g / seeds T2 = 30 g / seedlings and T3 = 45 g / seedlings. So there are 16 treatment combinations and repeated 3 times, which resulted in 48 experimental units.To determine the influence of each treatment and its interaction on the growth of banana seedlings, the analysis of variance (Test F) and continued with the test of Beda Nyata Jujur (BNJ) at 5% level.The results showed that the growth of good banana seedlings among 4 species studied was shown by Barangan bananas, but not unlike bananas. However, trichoderma administration until the age of 4 months has not shown the growth and intensity of different attacks. So it should be extended the study period to 6 months. After 6 months of research there has been a difference in growth and intensity of attack, where the intensity of the greatest attack is shown by T0 (without trichoderma). Medium intensity of smallest attack is shown by T3 (Dose trichoderma sp 45 gr / banana seedlings). The type of banana does not affect the growth and intensity of fusarium wilt attack. and the interaction of these two factors had no significant effect on the growth of banana seedlings and the intensity of Fusarium wilt disease.

Fusarium wilt, caused by the soilborne pathogen Fusarium oxysporum f. sp. vasinfectum race 1, is a vascular disease in cotton (Gossypium spp.), and is a component of a disease complex with root-knot nematodes (Meloidogyne incognita). Genetic analysis of two interspecific crosses (G. barbadense Pima S-7 × G. hirsutum Acala NemX and Pima S-7 × Acala SJ-2) showed that one major gene (designated Fov1) with allele dosage effect conferred resistance to F. oxysporum f. sp. vasinfectum race 1 in Pima S-7. Two amplified fragment length polymorphism (AFLP) markers were linked to Fov1 in Pima S-7, with genetic distance from the gene of 9.3 and 14.6 centimorgans. Less severe wilt symptoms in Acala NemX than Acala SJ-2 indicated that Acala NemX possesses one or more minor genes contributing to delay of wilt symptoms. Highly resistant plants in F2 and F3 (Pima S-7 × NemX) families indicated transgressive segregation effects of minor genes in Acala NemX combined with Fov1 from Pima S-7. The effects of wilt and nematode resistance on the nematode-wilt disease complex were assayed with two inoculation methods. In the presence of both pathogens, wilt damage measured as shoot and root weight reductions was greatest on wilt- and nematode-susceptible Acala SJ-2 and least in root-knot nematode-resistant and wilt-susceptible Acala NemX. Intermediate damage occurred in wilt-resistant and root-knot nematode-susceptible Pima S-7. The results indicated that nematode resistance was more effective than wilt resistance in suppressing wilt symptoms when either resistance was present alone. Nematode resistance combined with intermediate wilt resistance, as in the F1 (Pima S-7 × NemX), was highly effective in protecting plants from root-knot nematodes and race 1 of Fusarium wilt as a disease complex.

Abstract Legundi weed (Vitex trifolia) has the potential to be used as a biofungicide to control Fusarium wilt disease on shallots. For the manufacture of biofungoicides, legundi leaf extract was first fermented using the fungus Trichoderma harzianum. The aim of this study was to determine the effect of the method and dose of fermented Legundi leaf extract biofungicide on the Fusarium fungus that causes shallots wilt. The research was carried out in Senteluk Village, Batu Layar District, West Lombok Regency using an experimental method with a factorial randomized block design with two factors. As the main effect, namely the application of biofungicide fermented Legundi leaf extract consisting of two levels, namely: seed treatment before planting, and spraying treatment for plants aged 7 days after planting. Meanwhile, the simple effect is the application dose of fermented Legundi leaf extract biofungicide consisting of 5 levels, namely: 0.00 mL, 2.50 mL; 5.00 mL; 7.50 mL and 10.00 mL. The combination method and dose of fermented Legundi leaf extract biofungicide was repeated three times each, so there were 30 treatment combinations. The results obtained were the application of Legundi leaf extract biofungicides by soaking the seeds before planting at a starting dose of 2.50 mL to effectively control onion wilt disease. The applied biofungicide can increase plant height and increase the dry weight of the harvest.
